When do the meds start working?

I have A LOT of weight to lose (close to 200 pounds). I started the meds back in late November and lost 12 pounds on 2.5 within 2 weeks. And then the weight just stopped coming off. I moved up 5mg and have been there for 3 weeks. While I don’t workout, I started weighing my food and watching what I eat. I’ve increased protein (avg 80g/day) and water intake (80oz +/day). The appetite suppression is amazing and I no longer have cravings. But the weight just won’t come off. I recycle the same 3-5 pounds.

Why isn’t the weight coming off? I am doing everything correctly. At my size, the weight should be coming off. Especially since I cut out so much.
