Just curious if there are any words of wisdom before I start this morning.  I'm going to use mjshroomer's method from Erowid.  I've tried it once before with one foot of cactus, and provided very little effect.  I'm unsure if I was too hasty in the preparation or if that particular cutting was low in mescaline content. I also have no idea how potent these are, but I figure they'll all mix together in the prep, and I'll have more to take if it's not working.  
Thanks!
