And about not remembering much of it... DXM temporarily makes it very difficult for your mind to form new memories, so most of the time people remember little about their trips aside from random snatches of memory. Also, your body builds up a tolerance to it when you take it, so the second night shouldn't have been as powerful as the first...

What exactly led you and other people to think you were ODing? Where did you get your DXM, and what form was it in?

Sorry about the bad experience though... guess maybe drugs aren't good for everyone all the time...
