Hi Birdie,
To be honest I have found since my operation I am only slightly more 'windy' than I was before, and it's not as painful as it used to be. I can still belch, quite well in fact, and you will get a bit more down below - but you can be discreet about
it
I can understand you worrying about
the operation, it scared me too - you know it's going to happen, and you wonder how you will cope. I've said before my main issue was the shoulder pain afterwards - but it's short lived, and is helped a great deal by walking around as much as you can. They will give you pain relief too.
Fast forward 8 weeks - (that's me now) med free, reflux free and ready to go!
One thing to note though, as you are in the UK. Check if you get a post-op follow up appointment or not. If not, and you have problems, get on to your surgeon's secretary and make sure you do get seen! I just found out that it is not done in the trust in my area!
Good luck and let me know when you get your date.
