Hi and welcome. First advice: Look very carefully at why you are MO. Are you "simply" a volume eater? What co-morbidities do you have? How MO are you? These are the kinds of questions that should be influencing your surgery choice.
Do you have PCOS? Type II diabetes or any precursors? Do you have to starve yourself like crazy to lose weight? Have you been on many diets? These are signs that your metabolism might need more help than a restriction-only procedure can provide. In that case, it would be a good idea to look at the DS as an option.
