Okay, so I'm on 5mcg of levothyroxizine. (sp?) I'm very bad and just take it at night with my other meds. I know it says to take on empty stomach, etc. One of the symptoms that gave away my thyroid was hot flashes. It was hard to determine since I had a hysterectomy 2 years ago and am not on hormones, so I have hot flashes anyway. Here lately, I've seen a sudden increase in the hot flashes, especially at night. Trying to figure out if its going to be the hormone thing, or not taking my levo right or maybe I need to look into having my levels checked again? Anyone else not follow directions well and have issues?
