depression
"I went on the 300 XL version for about 1.5 years when I was in College. It improved my motivation/concentration/energy/mood, but I had hallucinations. Also, I did have a few severe major depressive episodes while taking it but my rebound back to "normal" was quick. I stopped taking the medicine for about a year- turned into the most severe episode of depression. When I went back on it, started at 150mg SR - no problemw, then back on the 300 XL and had terrible anxiety/agitation. Switched to 200SR- it's perfect. I'm not as moody/mopey/feeling sorry for myself. I don't spend hours on the couch. The fog is gone but I think I will ask my Doctor if I can take 2 x day- my fatigue/concentration are getting worse. Overall, great medication."
