I just went through the same Procedure, the doctor said the first 6 months are the worse. Per my doctor, the majority of the people who go through the procedure can not burt at all. He said I would hate him for the first 6 months. Try writing down the food you eat, if you get gas afterwords, don't eat it again for 6 months, You may need time to adjust, or you could have food allergies like I do. Tomatoes, peppers, garlic and heavy spices are universal trouble foods. Expecially if you have been on the Gerd or ulser diets, They are giving me trouble. I'm still in bland food and Lord help if I use a straw to drink or eat to fast.
