That happens to me when I smoke all day -- everyday.. but lately since I've been concentrating more on my schoolwork, I only smoke at night after I get all my shit done. Just cutting back has increased my highs.. I would smoke only during night or only during the day or else you have to smoke twice as much to get high if you get high at all. But yeah my friend who also sells to me smokes alllll the time and has the same prob. So either take a few days off or cut back a lot and then it'll make the high that much better
