Though I don't know the reason why,
chocamine really, really adversely affects my anxiety. It makes it almost unbearable at a high enough dose. The way it feels to me personally is like the feeling of being in love/infatuated with someone; that weird anxiety, no appetite, very restless sort of feeling that comes with being in like a new relationship or something. I know that's pretty vague, but it's the best way I can describe it in my personal experience. This may have something to do with the PEA content.
Still, though, lots of people love it for mood elevation and things like that. It won't break your wallet, so it's probably worth a shot. Lancelot's recommendations for extra supps with it are great as well.
