Lower dose works better?

I’ve been on MJ15 for a few months and my weight loss had stalled. I had no appetite suppression anymore. No satiety cues. It didn’t feel like it was working. I decided to titrate down and took 10mg on Tuesday. Why the heck do I now have little interest in eating right now? It doesn’t make sense. I really figured that I would have a much different experience. Anyone else go through this?
