I felt undescribably happy for no reason. I was at a music festival, took 1/2 pill and all of the sudden I was hit by a blast of euphoria and happiness, I started hugging everyone, my friends, strangers, even the security guard... I sat on the grass in the middle of the crowd and it felt amazing, I just could not believe how good I was feeling, everything was beautiful. Unfortunately, that ended when I started feeling heartburn and stomach ache, I have gastrointestinal problems and I was also drinking alcohol so that may have been the reason. It was very very cold and I just wanted to leave but I had to wait for my friends so anxiety started to kick in... omg I hate that shit.
