100% yes! I had the gastric sleeve and I was uncomfortable for a week after surgery, but moving and walking allieviated nearly all the pain. Post-op diet was boring but doable and the weeks went by quickly.
I would suggest finding a Protein suppliment that you really like the taste of, you will be drinking lots of it.
I am 4 months post-op and I have lost an average of 3 lbs a week. I feel great and I'm so glad I finally did something just for me, should have done it years ago.
