I had suffered from IBS for years and years since I was about 11. It got to be so bad that my lower intestine enlarged to a point where it was pushing up against my stomach and causing severe pain. What really seemed to help me is to take a capsule of flax seed oil with a meal along with a glass of water. It made it so that I was regular. In recent years, I've been doing research on just how many illnesses are related to the consumption of animals and their byproducts such as cheese and the like. In an effort to become a healthier and more compassionate person, I became a vegan and it has done so much for me!! Not only has it completely cleared up the IBS, but numerous other things such as hypoglycemia, acne, made my skin more healthy and radient, made my nails harder, I get a more restful night's sleep, I have a TON more energy, etc. I cannot say enough about how much becoming a vegan has helped my health but the most drastic of a chsnge that I have found is the IBS. Within literally two days I was regular without the help of anything. I didn't have to watch what I ate to make sure that everything would be okay either. It was and is awesome! About an hour after I eat I have to go and it is the biggest relief! I hope those of you with IBS take my advice seriously and just think about cutting at least some of the animal products out of your diet.
