No harm to a bit of a treat after :) I lost a load of weight too, was from November to March between diagnosis, acute cholecystitis then op, though symptoms a while before, I so don't miss that pain!
Amazing how effective a diet is when you have that as an "incentive', I was living on ham and wafer thin turkey salad wraps and sandwiches mostly.
I've out mine back and more but other factors for me like lack of mobility, steroids and other meds for other conditions.
It was quite a revelation though in learning to read labels in detail and how much fat is in so many things, especially ready meals, quite scary really!
I really like probiotics now, either in the low/no fat yoghurt or the Actimel drinks, especially when on antibiotics. I eat much healthier nowadays, just wish I could do more exercise to get the weight off, was so great to lose so much so quickly, although I had lost some quickly before and some say that can trigger gallstones to form.
Hope you have someone around to look after you a bit while you are recuperating. My mum came to stay after my op and was an absolute godsend! I'd have struggled without her.
Hope the air isn't too uncomfortable for you and keep an eye on the wounds. I had an idiot taxi driver who either didn't understand the request for no speedbumps or was really mean, getting home after my op, my main op would by my belly button opened (not as serious as it sounds!) and got infected but simple antibiotics job from the hospital walk in and then regular checks and special dressings sorted it.
I had two weeks off work and it was about right for me.
