You might be lactose intolerant, in which case taking lactase enzyme pills immediately before eating may relieve your discomfort.

Depends on what your tummy doesn't love about pizza.

Cheese? Lactose intolerance. Take some lactase.

Sauce? Sensitive to acidity or tomatoes? Take Omeprazole.

Bread? I'm sorry for your loss. It's gluten free or bust.

Depends on which part you're having trouble digesting.

Personally, I feel pretty darn good after eating a pizza.

If you aren’t lactose intolerant, this is something I just recently learned: chew your food very well. I know, it sounds like a given, but our stomachs and intestines don’t have teeth or any effective way to grind our food down into tiny pieces. Even something that seems softer, like cheese pizza, is a lot of work to break down into digestible pieces past our mouths. To some extent I have caused myself needless suffering by underchewing my food.

Weird way to think about it “drink your food, chew your drinks” let your saliva work on the stuff too.

If I eat specifically before bed...

That's the problem. You'd likely get heartburn after eating most foods if you eat just before going to bed. Don't eat that close to bed time and it shouldn't happen.

Don't eat within a few hours of going to bed. It's likely you have light acid reflux and sleeping with a full stomach, particularly when it's full of something so rich and acidic, will compound the problem significantly.

Also I'd recommend lowering the amount you're eating. Eat just until you're no longer hungry, not to the point that you're full. If you want an extra slice later as a snack cold pizza is awesome, but you can't un-eat the slice or slices that are punishing your guts.

That really depends. Which gives you more issues, greasy diner food without cheese, or a milkshake? If it’s the former sodium bicarbonate or bismuth subalycylate should help as will limiting your fat consumption earlier in the day. If it’s the latter try lactase

Piranha solution works good for that.

I use something called "Dairy digest complete" before eating any 🧀, because if I don't I spend an hour holding on to the 🚽 in fear of 🚀.

Have you tried sleeping on your left side after a heavy meal before bed ? Helps a lot with mitigating any digestion problems, due to how the digestive system is made

Lots of water, fibre and lactase

I wonder if I'm the only one who thought the title was a euphemism
