Levothyroxine
underactive thyroid
"I was finally prescribed this medicine after convincing my DR that all my symptoms pointed to hypothyroidism.  Since it considered subclinical at this point, he didn't want me to take medicine at all.  

I was eating hardly anything (no appetite - less than 1000 calories), exercising only 2 days a week because I was so tired even after sleeping 8 hours and still gaining weight.  On the weekends, I could accomplish a couple of things and then had to rest for a couple of hours.  My feet were so dry.  My joints hurt so bad it was hard to walk.  Life had become icky. I have been on this medicine for a little over 2 weeks and feel like my old self again.  I am not dieting, stopped gaining weight and can exercise 5 days a week. YEAH!"
