I have been fighting the Gas Battle for over a year. Read my posts, it likely wont let up much, we just have to live with it and learn to pass it. Probiotics can cause gas, along with starches and carbs. Eating carbs is like eating sugar a member here (Scott F) explained this to me. Carbs and starches will turn into sugar after digested and ferment into gas. Hopefully you find a solution, if you do please share. Now excuse me while I go pass gas for 20 minutes straight.
