ahh, my first time tripping shrooms the guy i got them off of forgot to take the cover off ofthe scale, so instead of 2g, i got more like 5g, took them all and tripped balls, it was his mistake so he was cool, but i wasn't prepared to trip that hard.
always remember, that when taking shrooms you are in control of your trip, (unlike acid) if it starts to turn bad just remember that you are tripping and make it turn into a good one,
have fun
