There is a website I totally forgot the name of it. I am sure some one on this board knows of it. Basically it has what known X pills contain depending on the designer. But ya it sounds like you got bad bills or maybe you should of taken the whole pill. I dont know if you plan to try it again, but be careful there are loads of fake pills out there laced with some evil shit. Like its been said before its almost impossible to know whats in ur pill w/o and testing kit. And you dont want to carry some testing kit around in a rave. Some people claim they can taste whether its a good pill or not. I guess some people can I cant. Just buy your stuff from well trusted friends is all I can say. Peace
