It just sounds like you paniced. I hate twitching, it really sucks. Try just smoking joints. I've learned that I can't take huge bong rips because I get a shitty high. If I take my time however, and slowly work up to that level of being high, it's a lot easier, because your reality isn't totally shattered. I just stick to joints and disolve my reality bit by bit. Get what I'm saying?
