Man... on this pill it makes me feel so bleh. The edge I use to have is gone. I'm not angry at the world anymore, I am for the most part pretty relaxed. Its suppose to help with concentration which it does a little, but not like others say. I have noticed a huge annoying increase in libido but at the same time I can control it. Here are the two negatives. Extreme suicidal thoughts, almost like its rationale. The other is feeling of being sick. I was hoping to become a super genius, but nope. Just normal thoughts besides suicide all the time like it's ok to do it.
