And, uhm, why didn't you just post this in the current thread about bwgen (that you started)?

Honestly, you're expecting too much out of it, I've tried every pre-set with sweet headphones, but it doesn't mess you up. Expect to be a little more relaxed than usual, but that's it. Don't expect it to make you OBE, or trip, or really anything for that matter, it's just an AID for doing those things. There's no reason to be worried, it's not as powerful as you think it is.
