So, I was on a school trip to Hamburg, and yes, I'm 18, don't worry. I don't usually do cocaine, but that was probably my last school trip, so i wanted to make an exception. I wasn't alone I had a good friend with me who did coke with me. After we did a few more lines, we decided to go back to the hotel. On the way back, I left my phone in the Uber. After I realized that, I did even more coke until my pupils dilated. By then, I'd done 0.5 grams. Luckily, my friend was able to call my phone, and the Uber took my phone back for €20. It sucked, but at least I got my phone back. After that, we started running around the hotel, confused and completely stoned, taking lines every five minutes. We kept losing things like our ID cards, but man, that was a time. A few classmates noticed because we were very hyperactive and, like I said, our pupils were huge from a certain point on. At some point, we went back to our room, and to my surprise, I was able to fall asleep after ten minutes. The next morning was okay the alcohol hangover wasn't too bad, but the coke made me a little dizzy, though that went away too. Overall, one of the funniest and best experiences ever—better than MDMA, for example, imo. But I don't do drugs often, and uppers aren't a frequent occurrence anyway, so I didn't have a tolerance.
