I started this drug 2.5 months ago feeling pretty good have lots of energy, a little trouble sleeping. The hair loss I had is slowing a lot and my hair is growing back and getting longer. I do have a complaint about joint pain especially in my elbow, but it moves around. Im taking vitamins and glucosamine msm. Its helping. Funny how the manufacturer doesnt list joint pain but so many people on this site complain of it.
