I use 'Forever' Aloe Vera Juice and have ever since I was diagnosed.
Before starting medication I went through excruciating pain throughout the night and day, and spent hours in the bathroom like everyone else, but what truly helped settle my stomach, relieve the pain and get me back to sleep was taking 1-2oz (a shot glass) of Aloe Vera Juice. Aloe Vera, the plant has so many health benefits and according to alot of research thats been done, can treat digestive disorders.
here is an article I stand by for Aloe Vera. I take 1-2oz every morning before breakfast.
You'll read alot of controversial subjects on Aloe Vera, but there is no side effects, there is nothing it can do, but good for your body. It has a gentle-laxative in its compounds but nothing remotely unsettling to the stomach. Tastes like water, you could literally grow the plant in your back yard, shave off the skin and put it in your blender.
From what I've learned, store bought brands are heavily diluted compared to some other brands, like the one i'm using.
