Admittedly, your description of symptoms isn't very good, but Pepto generally covers all of the bases. Are you suffering from heartburn too? Maalox Max is a product that combines calcium carbonate (antacid) with simethicone (anti-gas). It will take care of the burning and any bloating. That won't take care of the diarrhea problem, though. For that you need to turn to loperamide (brand name Immodium). Loperamide works by decreasing the motility of the smooth muscle in your digestive tract, taking care of the cramping problem. Kaopectate, another diarrhea solution, features the same active ingredient as Pepto-Bismol (bismuth subsalicylate), so you might as well stick with Pepto. I like the tablets.
