i would have to agree with moeburn, if you take your mind off of thinkin that you are gonna get sick then you should be ok. i over did it one night and smoke 2 fat blunts to the head and i felt like i was gonna throw up everythin i ate. i was so high and sick that i couldnt drive my car home i had to get my friend to do it. but i just thought about a bunch of other things and after awhile the sick feelin just went away.
