"Took all 4 pills with food.  I felt fine for about an hour and then the stomach cramps kicked in, I started to feel like I was gonna puke and ubered home as fast as possible. I puked and poo'd my way into remission and then fell asleep? Didn't even realize I had , experienced INCREDIBLY lucid dreams that I had no hands but was trying to call 911 to save me, it was so crazy I felt like I was on acid."
