<human>: Can you give me the gist of the text in a nutshell?

Okay, so I was diagnosed back in December with GERD, and my doctor told me it would help to lose weight. I'm 5' 8" and, at the time, was around 175-180. So, kind of embarrassed that my doctor told me I needed to lose weight, I went along with her diet with great enthusiasm - no fats, no eating 2-3 hours before bed, no alcohol, etc. etc. So, by the end of the school year, I had gotten down to 150! It was awesome. However, over summer, I haven't had access to a gym, and my work schedule has been so crazy, I haven't been able to pick a good time to make myself run. I've stopped working out, and with that, I've stopped caring about what I eat or any other rules given to me by my doctor. *Thankfully*, I haven't gained anything back. However, I am now at a loss. School's about to start, so I know I'll get back at the gym (fingers crossed) but I can't figure out good things to eat or good snacks. I'm on foodstamps, but I get $195/mo so I'm pretty set with food (I'm 22 and live alone). Does anybody have tips as to how to maintain a workout schedule with an unstable work schedule? And good, healthy snacks or dinner ideas? Really anything in particular?
<bot>: I've plateaued and can't remember how to get back on track. Maintaining isn't bad, but I've got 10-15 before my goal and I don't wanna give up so close.
