every one of these 12-month posts has the same buried line: lost the weight, and also stopped wanting to drink. sometimes the SSRI comes off too. the weight gets all the attention but the alcohol thing is the part I keep turning over, because the standard explanation doesn’t actually fit the timeline. the folk read is: you feel better because you lost 30kg, and feeling better means you reach for the bottle less. downstream of the metabolic effect. but the reports I find interesting are the ones where the drinking drops off in the first few weeks, well before any meaningful body comp change. that ordering is the tell. if the alcohol effect preceded the weight loss it isn’t downstream of it. hypothesis I’ve been sitting with: the appetite suppression and the reduced alcohol pull are siblings, not parent-and-child. both are central. GLP-1 receptors are expressed in reward-relevant regions, not just the hypothalamic feeding circuitry, and a study I read in rodents had GLP-1 agonism blunting alcohol self-administration independent of food intake. if that read-across holds even partially in humans, “tirz made me not want to drink” is a direct CNS effect and the weight loss is a parallel output, not the cause. which matters for how you’d read your own data. two axes people collapse into one: - metabolic: weight, waist, fasting glucose, the stuff that moves on a months timescale
- central/reward: alcohol pull, food noise, and plausibly the mood piece that let that poster taper the SSRI, all of which can move in weeks if you only track weight you can’t distinguish them, because by month 6 they’ve both moved and the story writes itself as causal. the n=1 version that would actually separate these: log alcohol craving (not just intake, the wanting) on a daily 0-10 alongside weight, from day one. if craving falls off a cliff in weeks 2-4 while weight is barely moving, that’s your dissociation. the free-text note on each entry is what carried this for me, being able to write “didn’t want it tonight, wasn’t even thinking about it” next to the number is the difference between intake data and craving data. CareClinic’s note-per-entry handles that shape. not claiming the mechanism is settled. but the reward axis and the metabolic axis are different questions and the deficit explanation gets applied to both by default. curious if anyone tracked the craving curve early enough to say.
the read-across you actually want already exists in the rodent work, alcohol self-admin dropping independent of food intake is the dissociation, but that’s exactly the arm nobody’s run as a clean human trial yet, so the n=1 craving curve is doing more inferential lifting than it looks. one thing i’d flag on the 0-10: “wanting” recalibrates against what you drank the day before, so a craving drop in weeks 2-4 isn’t fully clean of the intake drop feeding back into it. the free-text note helps with that bc “wasn’t even thinking about it” is a different signal than “wanted it less than yesterday,” but i’d log both the craving number and whether you actually drank, separately, or you’re back to collapsing two axes the same way you’re calling out on weight.
The rodent dissociation is the right anchor, and the early-weeks craving log is genuinely the only n=1 design that separates the two axes. Where I’d add a wrinkle: your two columns, metabolic and reward, leave out a third thing that lives exactly in the weeks 2-4 window you care about. The GI/aversive signaling. Early tirz nausea blunts intake of basically everything, alcohol included, and it does it on the same timeline as the reward effect you’re trying to isolate. So a craving score that falls off a cliff in week 3 could be central reward downregulation, or it could be “the thought of a drink sits badly in a stomach that’s already emptying slower.” Those feel identical in the daily note and mean different things downstream, because one persists after the GI stuff settles and one doesn’t.
The free-text note is actually what would sort it, if the prompt is right. “Didn’t want it, wasn’t thinking about it” reads very differently from “wanted it, but my gut said no.” First is reward. Second is aversion wearing a craving costume. Worth logging nausea on its own 0-10 line next to the alcohol number, because if the two curves move together in those early weeks you haven’t found your dissociation yet, you’ve found a shared upstream cause. None of that breaks your hypothesis. The rodent data controlled for food intake, which is the cleaner version of this same worry, and the pull still dropped. I’d just want the human n=1 to carry a nausea column so the reward read isn’t quietly inheriting the GI window’s signal. ymmv on how much that confound matters once you’re past month two.
the recalibration worry is real, and “wasn’t even thinking about it” being a different signal than “wanted it less than yesterday” is the right distinction to draw. but logging intake in a separate column doesn’t actually fix it. the confound you named lives inside the 0-10 scale, not between the two variables. if today’s number is anchored against yesterday’s drinking, splitting craving and intake into two fields just lets you watch them correlate, it doesn’t de-confound the craving figure itself. the fix is anchoring the scale to a fixed referent: rate against your pre-tirz baseline craving, not against last night. then a number falling in weeks 2-4 means something even if intake is also moving, because the denominator stopped sliding.

the part nobody’s chased here is the rest of the reward menu. if the alcohol drop is genuinely central and not deficit-downstream, it shouldn’t be selective to alcohol. the receptor read predicts the whole consummatory cluster moves together, because dopaminergic reward circuitry doesn’t cleanly distinguish booze from nicotine from compulsive scrolling from the 9pm snack pull. and the scattered human reports back that up, people mention nail biting, online shopping, weed, stopping at the same week the drinking falls off. so the control variable is sitting right there and it’s free: log one or two adjacent pulls on the same 0-10 against pre-tirz baseline. if alcohol craving cliffs in weeks 2-4 but the nicotine or the doomscroll pull doesn’t budge, that’s actually evidence against the clean reward-axis story, or at least says the effect is more targeted than the rodent self-admin work implies. if they all drop in lockstep, the central read gets stronger. intake alone can’t see any of this. you’d want the wanting, across more than one behavior, anchored to baseline not last night. ymmv on how many you can realistically track without it becoming a chore.
the within-week shape is the test I’d add on top of the day-one craving log. if the reward effect is central and direct like you’re saying, craving should reweight across the dosing interval, not just fall off monotonically with weeks. on a ~5-day half-life peak suppression lands days 2-3, so a direct CNS pull would dip hardest there and creep back toward trough, and that sawtooth riding the injection clock is a lot harder to explain away as “I feel better from losing weight” than a clean early drop is. a monotonic week 2-4 falloff is still compatible with placebo or just the food noise quieting and bleeding into mood. my window’s sema and food noise, not tirz and alcohol, so ymmv on whether the reward axis behaves the same. but the food-noise-by-dosing-day pattern only became legible from the per-entry note, the number alone hid it. a “4” on day 3 reads nothing like a “4” at peak suppression, and being able to log it off the watch complication is the only reason I caught the early-week dip in the moment instead of backfilling it from memory weeks later. curious if anyone’s craving curve actually sawtoothed inside the week, or just trended down across months. the first would be your dissociation, the second I’m not sure separates from the deficit read.
Separating metabolic and reward effects is crucial. You noted “appetite suppression and the reduced alcohol pull are siblings, not parent-and-child”, which resonates with my own experience of tirz quieting food noise early on.
