Hi mszyandry, and welcome to FitDay.
We've had a few members who have been through WLS so hopefully some will chime in.
Meanwhile, keep your eye on the prize. No, you won't have the immediate gratification of a lot of the foods you used to eat, but you will have your overall health and you'll feel proud for a job well done. It takes time to form new habits, but once you get there you won't want to go back to the old ones. Have you talked to your doc about your dizziness and shortness of breath?
I can share that I have a cousin who had WLS a few years back. She reached her goal a while back and I believe she's about half her previous weight. She makes getting her protein a priority and it's worked well for her.
Good luck! Hope to see you around the forums!
And now that you don't have to be perfect, you can be good.
