Try the 10 first. Did it for the first time last week (15x), and its a very intense experience. Go look up an FAQ. I was standing up when I did it, and got so out of it, I coulda did something dumb...so, ya....don't do that lol. I would recommend laying down.

The next night I did it when I was a little tipsy, and I must say it was a much better experience. No fear, or bad thoughts...I was lying down watching Fresh Prince, took a hit, and lets just say....the show came to life.
