I have rolled about 15 times on Ecstasy.. But that was about 2 years ago.. Haven't touched MDMA since.. I just picked up 2 grams of Molly and it was mostly in rock form.. I don't know how much I should take to roll hard.. Is 1 gram enough or should I take the whole 2 Grams?? Also, If I blew .2G and ate .8G, how long do you think I would roll for??
