My wife and I were talking about this the other night. I used to be able to scarf down 2, 3 burgers and a hot dog. Now, a single burger. Hot dogs, no more (big time stomach upset). Large portions of food period, no more {not a bad thing I guess}. Peanuts and Cashews, no more. Peanut Butter, no more...just hard on the gut. Ice Cream, cheese, dairy products in general, no more due to kidney stones. Alcoholic beverages, more than two now and I'm out like a light and usually waking up with an incredible headache. Coffee, I used to drink it like water, 6-7 cups a day, now 2 at most, hard on the gut.
