So going from 260lbs targeting 180-200 at 5'7" works out to a starting BMI around 42 and an ending BMI near 29. Age wasn't clear, guessing 40s based on context.
If it hasn't happened yet, a basic cardiovascular workup is worth getting, blood pressure, blood sugar, hb1ac, lipids, liver and kidney function. Mainly useful because worse numbers make early action more urgent before real damage sets in, and it strengthens the case for staying on this medication class for the foreseeable future. At a BMI around 42, metabolic syndrome and elevated heart risk are probably already in the picture, so cholesterol medication might come up as a conversation too.
Haven't come across solid proof yet that a lower amount or spacing doses out further actually holds up as a real maintenance approach over time. Trial settings with heavy support and monitoring tend to see smaller rebounds than what happens in ordinary life without that structure. And even those reduced-dose trials still show some weight creeping back, just less than stopping altogether would. Genuinely more long-range research is needed here.
