I don't like to eat that much when I'm high - the concept of 'munchies' is misinterpreted entirely by most people. You're not that hungry, it's less hunger and more desire to stimulate the senses. I find a spoon full of honey or a marshmallow go a long way when you got the stoner craves. Although, when I AM actually hungry while stoned, I really enjoy cooking. I try to be high during at least one preparation for a meal a day. The whole concept of preparing then sitting down and fully enjoying your meal is really relaxing - not to mention time consuming - really makes that time you had to 'suffer though' making food that much better. Then again, I don't tend to eat junk food so I guess I could be looking at this in an entirely different perspective : P
If you want something to enjoy while high, try making sure it's creamy - this utterly destroys mouth pasties - one sip of 10 percent cream cripples the uncomfort of dry mouth instantly.
