Yeah, I agree with 1234abcd. If you aren't getting a buzz from it then taking more may not be the best idea. Anything as strong as X can have very negative effects if you take too much. I've seen people who couldn't even finish a sentence after taking too many. They would literally lose track of what they were saying with EVERY sentence! Even though it went away after a couple days it scared me enough to determine that I would take no more than two pills per weekend.

Until it becomes legal or pure MDMA and we're not depending on someones bathroom chemistry I'll take my pills with a large safety margin. Have fun but party smart; don't become a statistic. Peace.
