@Ridgerunner,
While many bariatric post-ops are passionate about their own procedure, whatever it may be, the main reason you aren't finding a lot of SADI/SIPS patients who respond here (and elsewhere) is because it is a relatively new procedure and so there just aren't nearly as many people who have had the SADI/SIPS as who have had other types of surgeries. Also, there is a wariness of SADI/SIPS, not only because it is experimental and so long term results are not known, as mentioned by other posters, there have been a number of cases in which doctors have performed SADI/SIPS on patients who were expecting the DS.
I think its great that you are informed and know the uncertainty, but still want to be a pioneer for SADI/SIPS. Down the road in the long term, your statistics will help inform future patients' decisions.
I do hope you will decide to stay and contribute you personal experience here, as there will be other SADI/SIPS patients that follow and you will need to build a community and come up with answers for how to deal with post op life, particularly diet and nutrition as that is still largely unknown and will involve trial and error.
I've found the support of knowledgeable veterans critical in maintaining my health and expect you will want the same.
I understand it is probably frustrating to want to go down a certain path and have people respond with their recommendations to avoid that path, but I assure you, in knowing those people for years now, that they are well-educated in the topic at hand and have your best interests at heart. It would be less kind for them to be silent when they are concerned than for them to step up and deliver an unwanted message.
In any case, I wish you all the best!!!
