If you don't normally do, exercise. If you exercise than you're probably going to have to take it up a notch. I've noticed exercising gets rid of that drowsing after feeling of being high which is a good step to achieving more of a high. I usually smoke in the morning and at night. I suggest plenty of water and at least 15 minutes of exercise and you'll be happier. That's if you cannot handle a week or so drought which I wouldn't blame yah for not doing.

edit: I just realized this tonight^(wat i wrote above)^ and it brings back to the SOBER world which is where you want to be before you get HIGH.
