How is the quality of the bud you smoke? For me, that has most to do with my high. If I smoke shawg, I usually only get a headache and wanna go to sleep and thats out of anything I smoke shawg out of (blunt, joint, don't use bowls or bongs for shawg), now if you are smoking 15 blunts of nug a day, I say just take a break for little awhile, then start smoking out of the bong or bowl or just smoke 1 fat blunt every couple of days.
