It really is the choice for a happier healthier future! We all need to remember what that extra weight does to us now - but also way ahead through old age.
Re: varied recovery, I guess I was pretty lucky but I think going in with your eyes wide open - you're going to be sore the first couple of days. That wind pain is real. Walking as soon as possible helps it. Don't lie down completely flat in hospital ever. I just used the button for pain relief the first day - didn't get up to the loo til late in the evening - but by the early morning I could manage the pain without the button and because they can give IV Panadol that helped a lot.
Tell the Anaesthetist that you are really worried about vomiting post op and he will make sure he writes up stuff for you to have if you are nauseous . I felt that the first day or two but not since.
You can do it! It's a great step forward for your life. Good luck too Reetz you're this week too?!
