uhmm you cant really have a bad experience with E unless youve done it before and you take it and then it doesnt work... trust me its like being 7 year old and not getting anything for your birthday.... truley a horrible experience cause all the anticipation is built up

so no there is no such thing as a bad trip, if you plan on dancing make sure to drink water otherwise just drink a little more than normal, i suggest you get some photon lights and have a friend give you light shows.

if you start rolling just let go man dont try to hold back or you might stop rolling, XTC is funny like that, i swear 50% of it is in your head
