Gas pains are probably because your gut doesn't have enough cilia to breakdown your food in the large and small intestines. The food you ate is just sitting in there and festering...and causing all that gas. The pills you are taking won't help move any of that festering bulk out.... So you have to have another plan. Getting rid of what is in your gut and starting over. Think about what you are eating and drinking. Is it clean food? Does the food help you heal or is it junk food? Does it have preservatives in it? Is it fatty? Does it have any nutrients in it? How late are your eating? These are some of the questions that need to be asked to see if there is a pattern that needs to be altered to stop the gas from forming in the first place.
Resting your gut for a day may be an answer where you only drink your good clean foods like water with lemon, smoothies with only clean fruits and veggies. This allows your gut/LIVER to clean itself out. Check out some of the sites on this blog site that talk about how to do this.
