I've always gotten the munchie attacks (although the actual foods can vary- I remember one night where I ate three grapefruit in a row-best grapefruit ever!) but I've found that my lazy will win every time- if it's not in the room that I'm in I ain't hunting it down. I used to try to hide junkfood around my bedroom, Claudia Kishi style, but apparently my bad memory works just fine when it comes to food. I to try to keep water in my reach and that helps, but sometimes, you just gotta go with it, and hope you still fit in your fat pants later. I can't say if my actual snack habits have changed since my combustion days, so much has changed for me since then that I can't single that out.
(If I'm actually making a munchie run, I'm much more likely to come out with a bigass fountain drink or shushie variation- I'm always mildly thirsty and being high makes it that much worse. Or several drinks, because I'm indecisive under the best of circumstances.)
