Afternoon crash at the same time every day?

ok so like, i’m not just tired in the afternoon. i mean i get a hard crash between 2-3pm basically every single day, like i hit a wall. and it’s so consistent i could set a watch to it. my labs are…

fine. TSH is actually where my endo wanted it, free T4 in range. so it’s not like my levo is too low or something obvious. but the pattern is SO precise that it feels like something metabolic is happening at that specific time.

i take my levo first thing, eat breakfast like an hour later. lunch is usually around noon. then 2pm hits and suddenly i can’t think and my legs feel heavy. it’s not the normal afternoon slump that coffee can fix - it’s like my body just stops.

anyone else get these crashes at the exact same time every day? like are you tracking what might be causing it - cortisol rhythm, blood sugar dip, something about how your meds absorb? or am i just broken lol
