As someone with a really sensitive stomach and borderline IBS symptoms, Pepto-Bismol really is your best friend in times of crisis! As soon as you feel the gurgles (which sometimes, can be too late) chew a couple tablets and pray they hit your stomach faster than it expects. They always seem to work very quickly and after about 5-10 minutes the gurgling, cramping, pre-diarrhea signs disappear. This stuff has saved me from many explosions due to whatever issue my body is having haha. The times that it hasn't been easily accessible, I really regret forgetting it at the store. Totally recommend! Even if Pepto is taken too late during an upset stomach, it can help relieve the symptoms while they are happening and end the torture much quicker. It's never too late to help your bum!
