What's the upside to going back to having carbonated beverages? I know it's acedotal, but of the people that i have spoken with that had significant regains, the first thing they talk about doing when they "went off the wagon" was starting to drink soda again. I have read so many reports about the determental effects of carbonated drinks, even those that are sugar free, It also makes perfect sense to me that there is the potential for sleeve expansion with the increased gas which will be in the stomach. Additionally be very carefull if carbonated beverages and soda where something you drank alot of in the past. Testing the waters with it now may very well lead to a place you don't want to be. Don't make it a trigger food.< /p>
