"i&#039;ve taken elavil for 14 yrs for irritable bowel syndrome and depression. i suffered with ibs for 5 yrs and had every test  possible and even had my gallbladder removed. it really makes me sleep but after taking it the 1st night, i knew it was the magic medicine for my irritable bowel syndrome. as long as i take 25mg each night, i have zero irritable bowel symptoms. it saved my life."
