any previous experience with other drugs??? weed? LSD? My thoughs on this is... if you have no experience whatsoever, take 1g... if youve smoked weed a couple time... take 1.5-2, and if youve done acid or peyote or something... take 2.5+
I aslo ate 5 g's my first time. Lost my mind too, but that was becuase I was alone at night in my parents house when I was like 14, man was I in for a suprise when they kicked in hahahaha.
It really depends on the type of shrooms you get. Some are more potent than others. Oh dude check this out. http://shroomery.com/
First time, take half an 8th man. That way you won't regret it...that's what I took my first time and I had a damn good trip. The thing with shrooms (this may be just me) is that even if you're having a great trip, you still have times that you feel like shit...ie your stomach just starts twisting around. Anyways, try half an 8th man...anywhere between 1.5-2 grams and you'll still have a great time.
