I need to make as much money as I can in 3 months at rehab.
I am moving to rehab against my willing and I need to make as much money as I can while there cos I'm planning to rent my own place when I get out of there. I'm still living with my parents so they house their rules so I'm moving the shit out of here when I'm back.
I have several SBCs and VPS making passive income while I'm there so when o get out I will have enough for a couple months of rent but I need to make more money while at rehab.
What country are you in? Are you talking about a sober living home? Usually in rehab you don't get a job, you just do therapeutic activities and focus on sobriety then leave.
When I was in rehab I got a cigarette injector and would sell cigarettes. They regularly made runs to the smoke shop for us and took shopping lists. Yours may or may not but it was a good source of income and good for bartering.
Reading, drawing, playing card games were mostly how I passed my time. I'm assuming that since you're going to rehab you know how to play spades but if not I'd highly recommend learning.
They're of course going to give you a lot of coursework too so you can look forward to that.
