The more fills you have and the more restricted you become, you will find you cannot physically drink while eating anymore, even if you want to. I've always tried to drink right up until I eat, then put my glass away. You will get used to it over time, and like I said, eventually you won't be able to do it because the liquid will not pass through the food, and comes right back up. I experienced this while eating at a restaurant and "forgot" to remove my drink and out of habit, reached for it. I had to spit it back into the glass. Not a pretty sight!
