can you have seltzer water on pre op diet?

Soda is a big factor in weight loss and gain. It wouldn't seem so with no calories. But it appears to be very addicting. (And lots of very heavy people drink much sugar free pop. )
It is a common post about wanting and giving it up on here... most docs seem to say no.
Lots of patients really want it and post here about whether or not to give it up

So I had emailed the nutritition ist and she said SEltzer is fine. That being said I found a zero cal flavored Water at costco that

tastes good and isn't too sweet Kirkland Brand!
