Kit 5, month 3 and no results

So I’ve been on kit 5 (topiramate+ B12 and metformin) I’m assuming since I’m already prescribed bupropion for anxiety/depression and that’s in some of the other kits. I haven’t seen any results or curbing in my cravings. I’m mindful of what I eat, use myfitnesspal and have lost weight doing just that in the past plus exercise but I’ve never reached my goal weight. I’m close to my heaviest weight right now due to my binging being pretty bad in the months before I started hers and also having a surgery that didn’t allow me to exercise. Anyway, I’m now on month 3, close to month 4 and haven’t lost any weight. I don’t have a perfect diet but I certainly have been worse and weighed less. I work out on average 3 times a week. But this has not curbed my appetite at all. I reached out and all I said was I hadn’t lost weight, and they started asking me if I was working out everyday, eating 100g of protein a day, etc… and I said no not every single day but I try my best. I guess they took that as this was my fault. They said I should consider cutting white carbs (THIS is the part that upset me) and a couple other things, eating lean protein (I already focus on this, I get a lot of protein) and this really frustrated me. I totally understand if I was eating like trash and in a heavy caloric surplus in addition to this medication and not seeing a difference then that’s on me. But that is not the case. Why am I expected to restrict and cut out foods in addition to the medication… then what’s the point?? Of course cutting carbs would make me lose weight, but if I wanted to cut carbs I wouldn’t be spending $300+ on medication. Am I being unreasonable?
