Hi Linda,By the time you read this you'll be an honorary member of the Healing Well Wrapped Club! It sounds as if you're long overdue for the surgery, so it's obvious that you've made an excellent decision!
If you haven't already seen it, you might find my early recovery journal helpful as you go through that recovery yourself...

Stick around! This is a great forum with lots of experienced post-Nissen members!
As Joy said, if you can surrender to your recovery and follow its lead, you'll do just fine. Those who struggle against what is, and try to rush the healing. Your body will decide the pace of your healing, and you just have to go with the flow! We're here to offer support and share our own post-Nissen experiences.
Happy healing!
Denise
