Hi,
I got the lap band when I was 20 and I am now 28. I always struggled with this.
My doctor always said never to drink carbonated beverages but I can drink beer and champagne.
Back in my early twenties I was able to drink a ton of fruity drinks and have no problem. Now all I seem to drink is wine and champagne drinks- mimosa and bellinis. I have a hard time drinking anything that has acid in it. It gives me really bad heartburn.
Also, make sure you eat at least an hour before you start drinking. Being that it takes a long time to digust your food you don't want to be throwing it up because you didn't wait long enough.
My big thing now is that I always make sure that if I am going out to dinner to have my one glass of wine before the meal. This way I am able to have the one drink and I don't have to wait the 30-45 to start drinking again after dinner.
This is a huge adjustment and a learning experience.
Good luck!
