Take Phazyme, over-the-counter, I couldn't live without it, I have IBS and terrible gas buildup and constipation sometimes. Also, I take Papaya tabs or other digestive enzymes, it makes a world of difference -- plus -- DRINK LOTS OF WATER! (not overly much, but I drink 2 liters a day, at least) That moves things through. If you are taking a fiber supp, take the liquid one and follow it with more water. I can't take the fiber pills at ALL. If I am not careful with the metamucil liquid and flush it through with plenty of water, I get a "stuck" feeling.
