Levothyroxine
"I was diagnosed with subclinical hypothyroidism a week and a half ago. I'm 21 and slightly over weight. My thyroid levels were tested because I sweat excessively. I only felt dizzy on the first two days of taking this medicine. I always feel tired right after I take it, but that goes away after I work out or concentrate on something. After about 3-4 days of taking it, I noticed that I was sweating less! I think I'm slimming down (but that could be because I have had more energy to exercise). I take .025 mg. I'll update in a few weeks!"
