underactive thyroid
"I've been taking levothyoxine for a week and a half now and before it I would fall asleep at work, when I was driving, just watching tv. There was a time that I went through 5 different sleep medications in 2 months to try and figure out the right one because nothing was working for me. My whole body ached, and worst of all my hair was falling out. The first couple of days taking the medication my body ached really bad but it got better. I lost 12 pounds already and my hair stopped falling out. I also am able to get through the day without falling asleep and because I don't fall asleep during the day I get tired during the night! I love it."
