Six weeks off my prescription and my dorm fridge is the boss

I'm a broke grad student in a dorm with one microwave, a mini rice cooker, and a fridge shelf that sounds like a wind chime every time I open it. I stopped my prescription about six weeks ago after talking with my prescriber. My last shot-day weight was 183.4; this morning it was 184.8. Not the dramatic rebound I feared, but my appetite has definitely turned the volume back up. Cheap-protein rotation: egg salad with mustard, tuna packets, frozen edamame, lentils cooked in the rice cooker, and a tub of plain Greek yogurt I portion into little reused jars. It's not glamorous. Yesterday I ate chili-flavored tuna on a rice cake and felt like a raccoon with a meal plan. The main thing helping is eating on a loose schedule before I get ravenous and keeping the dorm snacks out of sight. The vending machine downstairs knows my name now, which is concerning. For people who've stopped, what cheap dorm-friendly protein actually helped you stay steady when food got loud again?
