For the past two nights my stomach has been feeling weird, like a bit tight. There's a faint pain, but not so bad. Also I'm a little bit nauseated. In the mornings I have been drinking a lot of coffee and was wondering If that could be thr cause. Also, I'm taking an allergy medicine called Talion tablet. I think thr side effects are nausea and stomach agitation. So..I wonder if it's from thr coffee or the medicine. Any ideas?
