Possibly.: Either of these can cause GI side effects, so it is not clear what is going on in your situation. I would stop both of them for now. If your symptoms go away, and if you want to restart either of them in the future, do it slowly, one at a time, and see what happens. Depending on how much caffeine you've been taking, you may develop a headache for a few days when you stop it. Good luck.
