Welcome to the Healing Well GERD forum! Joy knows what she's talking about and has given you some great information. There are lots of members here who've had the surgery and know what the recovery is like. Be sure to keep posting your questions and concerns.
Here's a link to my early recovery journal and some thoughts about the surgery. Hopefully it will answer some of your questions, and alleviate some of your concerns.
Again, glad you've joined us! It's a great group who will provide you with lots of information and support as you travel the road to recovery.
Words of wisdom by Eckhart Tolle:
"Whatever you fight, you strengthen, and what you resist, persists.”
“Worry pretends to be necessary but serves no useful purpose”
“Accept - then act. Whatever the present moment contains, accept it as if you had chosen it. Always work with it, not against it.”
