Unfortunatly I have had an experience like yours. This past August my friend and I went to the Hamptons and stayed at a friends house. There was about 10 of us, and we all popped a few pills. We went to a club out there, we were there for a little while and decided to leave. By the time I got back to the house, Iwas on 3 pills. We decided to go swimming and in the jacuzzi. Well, I think I got out of control, I dont remember how many pills I had. All I know is by 8am, I was still in the jacuzzi with a few people. The next thign I know, I had to sit out of the water on the edge of the jacuzzi. My heart was pounding so fast, it felt like it was in my throat. I was so dizzy! Next thing I remember is one of my guy friends helping me out of the jacuzzi and I remember running to the corner and throwing up! I have never gotten sick before on pills. That was the worst experience in my life! I litterally thought that was it for me. I didnt sleep for almost 2 days! Every since then, I rarely pop anymore, and if I do its only 1 or 2 pills.
