The hardest part of dealing with the munchies is finding something to munch on!! I find it really useful to keep snack portioned (about 100+ cal) food around the house. I know that it’s cheaper to buy in bulk, but when I open a full size anything I never stop at the snack-servings! It’s just too tempting to finish it all.
Especially when there’s a sad cling-wrapped can sitting in the fridge looking at you accusingly, going, “You left me you bastard! YOU ABANDONED ME!!!”
Which is why I also find it a lot more satisfying when I finish a full serving of snack portions. That, and I have a strange satisfaction seeing empty cans/bottles/packets in the bin.
