If you pour the drink over ice & tip it between 2 glasses & then swish it round with a straw-to get the worst of the fizz out & drink it slowly-i've always been ok after doing this! Also i asked my surgeon bout this (as it's how i drink my Jack Daniels lol) he said it would just give you nasty wind pain if you drank it really fizzy.
Yes, that's one of the things i really struggle with! Every since you begin to eat solid foods as a child your always given a drink to. It's a tricky habit to break.
