I hate to admit it, but being constantly in the company of a heavy smoker, I've got into the habit of smoking myself. There is no pattern to the time of day in my smoking. I only do it when I feel the need. Sometimes I might go a few days without smoking, while on the days I do, I might smoke anything between five and fifteen. Initially I used to feel lightheaded after smoking, which I guess every new beginner feels. I don't experience any such fuzziness anymore since I've started taking it regularly. I try to keep it to as less as possible but sometimes I realize i do go over board. At what level of smoking should I know that it's getting too much?
