Irritable Bowel Syndrome
"I have bowel adhesions and they cause debilitating  IBS. I first was given Donnatal Elixir in an ER with horrible intestinal cramps.  This stuff soothes, works quickly and it stops the cramps.  I recommend it to anyone I know who has IBS.  And the drowsy side effect helps me to sleep and when I wake up I feel better. 
Definitely ask your doctor about this one if you suffer from intestinal issues!"
