I go to a gym/weight loss center run by a bariatric surgeon. They also work with non-WLS clients, and offer an Adipex (name brand phentermine) program as well as an HCG program. I talked briefly with them about what would my options be if I hit my goal weight and want to lose more but have trouble (still 98 lbs away, so it was hypothetical), and we all thought the Adipex would be less effective b/c of malabsorbtion issues. The HCG program, however, has a strict 500 calorie diet for 3 weeks, and they weren't sure if that would be feasible either, also because of the malabsorbtion. This was all assuming I was still in the malabsorbtion period. So we left it as something to discuss further down the line, if it's even needed. I wouldn't be opposed to trying either, so long as I was being very closely monitored.
