lots of bread! it isnt that unhealthy and fills you up fast, put a little peanut butter on it to make it even better. you could buy healthy bread instead and low-calorie peanut-butter, it wouldnt make much difference if ure high. i find that when i havent been high for a while i dont really get hungry, its worrying because before i started smoking i felt a little hungry all the time but i guess it balances things out. And also try to time getting the munchies with eating a normal meal.
