Nortriptyline
"Started taking nortriptyline for chronic pain and noticed all my IBS with diarrhea symptoms were gone!! Bonus! It was so dibilatating and painful, I was miserable. Constant pain, bloating, cramping. This drug has saved my life! It also treated my chronic fatigue. For most people it makes them tired but for me it was the opposite. So very thankful. Three problems fixed with one medication! However, it has increased my heart rate and worsened my anxiety. And also squashed my sex drive. That sucks! But the benefits out weigh the negative."
