Are "instant feel good" ever actually good?

ugh... why did I do that? Now I feel like crap and well... have mild remorse! I just inhaled the leftovers (kind of a lot) of ice cream in my freezer along with Kashi Heart to heart cereal.. (I really have a thing for cereal!).. And well that's what I get: stomachache and an extra pound on my hips. It seem to only happen when I watch TV(on my computer) too... Maybe I should just stop watching stupid shows..
