depression
"At first I had a pain in my left hand while taking it and almost stopped. Glad I didn't because after a couple of days this went away (mostly) and I started feeling the good effects, most notably is I didn't feel tired during the day, that was a part of my depression so this did have anti-depressant effects on me. I was happier doing everyday things like washing the car, I started cleaning the house at random and found it enjoyable. I do get an occasional headache or pressure would be a better description, so I occasionally take 1 advil with it and it goes away. I noticed, for me, this drug only works when you take it as prescribed."
