Oh my, I've been drinking soda for years. Well, at least since I got banded in 2010. I like a diet 7-up with gin. Or whipped vodka with diet root beer. Only when I have alcohol. I do stir it around and get a lot of the carbonation out. I haven't had any issues. What would I look for? I do have a lot of reflux. But, I have that regardless of whether I've had any soda.
