Weirdest thing - I used to be able to drink soda, beer, etc without issue. Now, as a dude in my mid-twenties, my stomach has a tough time dealing with it, it seems. When I drink a beer or soda, I get almost immediate cramps (not severe, but very uncomfy), massive gas, and a very upset stomach. What's the deal? It seems to happen when I drink dairy products (milk and coffee with dairy in it) as well - but not when I eat some ice cream. What the heck, man? And yes, I know the immediate solution is to stop eating this stuff. Just curious...anyone else have this issue as well?
