I would agree. I'd revise to a DS. You probably need that surgery. I don't think you will be happy with the RNY and think you will likely not get to your goal weight with it.
I can say this because I have RNY (virgin surgery) and have a larger capacity. So I do not feel a whole lot of restriction. And food goes through my stoma very easily. So I have to be extremely careful of what goes in my mouth, calorie, volume count and limit food in the face of hunger. And I got to my goal. But it took iron balls to do it. And not everyone can put that kind of limit on themselves.
If you haven't already, you need to have your sleeve evaluated to see if they left too much of the fundus in tact, or if it can be revised to make the sleeve smaller in a re-surgery. If it's surgeon error, they should have to fix it.
If it's your error through overeating or eating around restriction, then a new surgery won't necessary fix your head and you will need to consider counseling along with a new anatomy if you want to avoid having this same discussion in the future.
