well, here i will pose to you this question. Do you smoke until you get uber stoned every time, or do you smoke till you get buzzed? For a few months i would smoke until i got really stupid, everytime, then i started smoking until i got buzzed and i enjoy smoking more than i did before, not to say i dont get really stoned anymore, but most of the time i will smoke only a few hits out of a bowl, then rest for a few minutes, then take a few more.

taking a regular break helps as well, i tend to smoke a week, take a week off, then smoke a week, and another off week. it helps keep me regular.
