try using a gravity bong or pretty much anything that gives huge hits. what do you use to smoke with right now? whats your weed like? if its brown, all ground up(not buds), smells shitty or no smell, or any of that, than thats your problem.

so pretty much make sure youve got at least decent weed, and make sure your hits count. if you've never tried it, you should smoke a blunt. those things fuck you up! oh and one more sugestion, i know alot of people are against this, but adding tobacco to your bowl (mix a small bit with your weed) and it really adds to the fucked-upness
