Welcome to Healing Well. Glad our posts were helpful! Yes, you will be able to eat bread and steak once your healing has progressed. You will have to always eat more slowly, and chew your food more carefully.
As far as soda goes, I do think many people go back to drinking it, although perhaps with more moderation. I'm not a soda drinker, so I'm not a good one to ask. I do drink beer on occasion, and that carbonation doesn't bother me.
Once your body has had a chance to heal completely, you'll feel pretty darn normal. There may be one or two little quirks you notice, but overall it's not big deal.
If you've suffered from GERD, you'll find any little inconvenience very unimportant, and you'll truly appreciate being GERD free.
Good luck with your surgery!
