I cannot handle hi-fibre either. The gas and pain and bloating are unbearable. Like KOKO said, it's individual. Making sure I get enough good fat and LOT of greens and veggies usually keep me regular. If you want to try a supplement to help you out, magnesium is great!! Most people have a deficency and don't know it!! Just get some good 'ole Milk of Magnesia. Start at the lowest dosage and raise it until you find what works for you. After time as a deficency rebuilds it's self, you'll notice the amount you need will decrease as time goes by. DON'T start at the highest dosage!!! You want regularity not a continuous flow!! It's cheep and good for you!
