I had a SADI…
I think you will be fine. The restriction will limit you to about 600-1000 calories per day. That will create a calorie deficit. Weight will come off.
the VSG was once part 1 of the DS. The DS was often done in two surgeries in the past - they'd make a sleeved stomach first, then would go in a few months or a year later and bypass the small intestine. But enough people lost enough weight after surgery #1 that they started offering it as a standalone surgery - and the VSG was born. Long way of saying - doing something like this in two parts should still work fine. I know you're wanting a SADI instead of a traditional DS, but the same should apply.
