My new GI doctor and I were discussing when the best time to take fiber supplements would be for me, and he started talking about what has worked for him, and I asked him if he had IBS, and he said, "why do you think I went into this field" He was so compassionate and understanding, when he told me he would cure me, I almost cried... For all other C types, he had a really good idea, I'm sure many of you have tried this, but for those like me who havent I thought it made sense. Basically a spastic colon trappes air and stools all through the colon, not only at both ends.. this explains why some people suddenly have spasms leading to loose bowels, others have constipation, gas gets trapped so easily... so I was taking fiber, which was only making it worse, because while fiber can cause bulk, along with magnesium, aloe juice, etc... it doesnt matter because the colon will still spasm, bunch in certain places, trap those stools and even more gas.. so the solution is fiber along with anti-spasmadics. This way you get bulk, and once your colon relaxes, gas and stools can pass through more quickly... I think the combination of the two sounds great, has it worked for anybody else?
