Can I drink Pepsi Max prior to Rhinoplasty?

I see absolutely no reason why you can’t! (As long as not 12 hours before surgery as obviously you need to be starved before your general anaesthetic)

For my opinion, you don't recomend the patients to drink acidic drinks such as cola. Because in surgery there is a risk of peptic ulcer. We give routinely anti ulcer treatment for prophlaxy.
