underactive thyroid
"I have been on this medication for 5.5 years and at first I'd felt great. Things were going well until 3 years ago when I'd started having side effects. Weight gain every year (10 lbs) even though I'd worked out and ate pretty healthy, couldn't sleep, depression gotten worse, mood swings, some times I wouldn't have a period, extreme fatigue, brittle nails and muscle ache. Every time I'd taken blood work, the test came out fine. I'd gotten tested for everything else and nothing seems to work. Just recently, I'd started crying myself to sleep because of the mood swings. I'm also falling asleep while driving because no amount of sleep kept me up. I'd finally did more research because my Doctor only suggested two medication. I'm calling today."
