same shit happened to me....and probly all e users...trying to attain that first few times of euphoria...i have no tolerance either....but you probly get more dopey now....trust me man, just give it a rest.....you will start feeling really moody and stuff....it's not worth it....e should only be take 4-5 times a year....thats it, if even that. You will burn out....and youll start feeling like a traitor to the scene, becuase you always take drugs when you go....doing it every weekend is really, really, really bad.....and you should also not go back to the club for a few weeks, then go back sober....that way you will have forgotten about it, and when you go back sober, you will have a really good time. You'll then ask yourself, wow, I really don't need the E. Plus, the comedown really isn't worth it. You'll see. Be safe, and smart.
