Come on dude, you know the answer to this. You just want people to tell you you are fine.

Stop drinking so much. Walk around a lot, then try running when you feel that you won't have a heart-attack from doing so. Eat better. Maybe swim once in a while. Etc.

Don't eat within 2 hours before going to bed!

EDIT: Stay away from butter, sour cream, dressing, etc. I know it's hard but try it.

I eat potatoes PLAIN and pancakes with no butter or syrup. Yeah. And I never eat Sour Cream. I use minimal dressing on salad.
