Hi,
I am 6 days post op bypass & gall bladder removal,& came home last thursday evening , I seem to be having similar problems but due to the severity of what we have just had done this is to be expected.
I also couldn't stand the smell of anything perfumed for the first three days without wanting to vomit.
I have found it best to carry on as normal but in a slightly gentler fashion so , first day out grocery shopping on Friday was cautious , Saterday at Wetherspoons for a lat'e was a treat, Sunday christmas shopping a little weary but by today no wind pains only slight discomfort from what feels like an air bubble just above new tummy when drinking,.
Take it slowly , you have had your internal plumbing re-structured.
As Mr Shroeder said to me .... this is a time to heal, you have wounds that you cannot see and will take a while to re-couperate.
chin up - it will get better through time.
