Question about pre-op diet

I wanted to know did anyone have any trouble when it came to their pre-op diet. I have not changed everything at once but I still find it hard for my evening meals. I have no problems during the day it's only with my dinner that I'm tempted to go overboard with the whole thing. Can someone who has already had the surgery share with me.

Nikeeta, could you let us know who your surgeon is? That way, folks who are familiar with that surgeon's routine might be able to help. Also, when are you having surgery?
