I haven't had any bad trips with it...yet. I just started using it so I started with 8 of the cough drops. The first time was really weird. I didn't know if I liked it or not...but I was only on the 1st plateau. Then the next two times I did 14 pills. That was a hell of a lot better of a trip. I even had the awesome walk going on. The first time I did the 14 pills I was watched 3 movies until the stuff wore off...I wasn't sure how I was going to be affected. Then the second time I use 14 pills I was camping with some friends. We were suppose to get drunk that weekend but I kind of figured they wouldn't bring the beer so I brought some DXM with me. They didn't so I took the pills. I was hyper as hell. It didn't kick it for 2 hours and I was worried that something was wrong but it was the best trip ever. The pills were only 15mg so 14 pills is not a lot...just the 2nd plateau but the bad trips happen during the 3rd plateau but I'm going to do it soon. I'll tell you how it goes.
