To help with the fatigue, taking a magnesium supplement daily is wonderful. I never was that into vitamins, but this one has helped me so much. It also helps prevent headaches, especially migraines. And one beneficial side effect is it keeps you "regular". So it might help with the gas buildup as well. For faster relief of the gas pain mix a teaspoon of the spice Ginger with a 1/4 cup water and drink it. Follow it up with something that tastes better. Or you can even buy ginger candies, which taste better and work the same. Avoid carbonated beverages until the buildup has subsided. I hope this helps a bit! ^_^
