Hi and welcome, I had a sleeve in August. The surgery was fine, I was a bit sore the first few days, I didnt use any painkillers at all so gives you an idea of pain levels. I was tender.
Make sure you take it easy for several weeks afterwards..you will be tired and lacking energy.
I did 3 weeks liquids, the main issue was getting enough in throughout the day, it was sip sip sip.
Then I had 3 weeks puree, that was the worst bit, blended food it vile..i stuck with danio yoghurts, fish in sauce, cottage pie, weetabix, thick soup like carrot and coriander, oh and beans with mini sausages.
I then moved on to solids.
I have been really pleased so far..every day I still think about what I will eat but food doesnt take over now.
Good luck you will be fine..just do as they tell you.
