on 75mcg levothyroxine for 8 months. TSH is 2.3 (textbook perfect according to my doc), free T4 in range. but i still completely crash 2-3pm every day.
like, can’t focus, energy just drops. at first i thought it was just physical work (i’m a carpenter) but it happens on rest days too. started wondering if once-a-day dosing isn’t working for me, or if the T3/T4 ratio is off, or if there’s something else entirely i’m missing.
has anyone else been there, where the labs look fine but you feel broken? how did you actually figure out what was wrong? was it a med switch, different timing, splitting the dose, or something completely different i’m not thinking of?
