Did you continue to track calories while using the drug?
As somebody who has successfully increased and decreased their body weight over the years (after initially being obese), if you’re able to diet consistently I don’t see why a drug is needed. My guess is whatever diet you were on was consistent for the weight you were at.
I had better luck with Weight Watcher with "free" healthy foods and the segmentation between weekly and daily budgets. Then weight watchers tweaked their point values so much that I couldn't stick with it very well, and when I dual tracked points and calories the new WW plan had me at under 1400 cal/day, which isn't sustainable.

It'd really really really really really really hard to stick to a diet, especially long term. GLP-1s puts eating healthy and good portion sizes all on autopilot. I don't have to plan out how I'm going to manage my hunger and my food noise, it's just auto pilot. I naturally gravitate to eating enough, but not too much, and mostly plants.
If I was shorter, female and sedentary, sure. But that's not me.
