Meds stopped working?

I have been taking sema since June, 2024. I have started to take 2.4mg since early December. However, i’m finding that the food noise is coming back, I’m eating more than I was before, and there’s been sugar cravings. I’m not sure what’s going on, but I hate that I can’t stop thinking about food. I’m also struggling with seeing results on the scale. I have lost 1lb in the past 2 weeks even though I have been trying to be mindful of my food. I have been exercising and walking consistently and making healthy decisions as much as I can (I’m a grad student so on a very tight budget). I even just ordered my 2 month supply of sema ( I use OrderlyMeds) on 2.4mg, but i’m starting to feel that this isn’t working anymore. Am I being inpatient? Should I continue on for the next 2 months? I guess i’m just wondering if that has happened for other people, what they’ve done or what they would recommend?
