I used to drink a lot of soda and it started making my stomach feel upset, but for the past month I switched to gatorade. I drank a can of coke this morning after I ate my regular lunch because that's all I had in the fridge. After drinking the coke 1 minute later I felt kind of sick, a few more minutes later I threw up. My question is can soda cause you to throw up? Since I drank too much before I'm thinking my stomach just had enough of the soda.
