Well, I just spent an entire weekend sleeping. I had RAI 3 months ago and been taking synthoid. I noticed Saturday and Sunday I slept the entire weekend except for 10 hours. I have put on 50 lbs and feel disgusting and none of my clothes fit. I called my endo on Monday and went and had my blood taken on Tuesday. I hope that they up my dosage of Synthoid because I hate wasting time like that. I don’t have to eat abnormally to put on weight…and am to exhausted to exercise. Well I guess it is better than the bloating, chest pains, heart attack and rapid weight loss I endured in the beginning of the year but does this ever end?
