I got some good coke. And the first 10 minutes it was a good feeling. But then it turned into a bad feeling. Can't really explain it but, the first 10 mins it was euphoric then it was a speed high that I hated. I was like rubbing my forehead and pulling on my shirt collar saying to myself "I hate the way I am feeling right now". I would have to do another line or two to get that feeling to go away. Did I do too much? Was the coke too good? Was there a cutting agent that was making me feel that way?
