Congrats on over 2 months!! That's amazing!
It sucks when you're the one in a group who has your feet proverbially under yourself - especially if you were in similar circumstances earlier and have now got a better handle. You don't have to take on more than you have, including making wake-up calls for adults who strictly ought to be taking charge of their health by being compliant with medication, or cleaning the house for people who (it sounds like) could do some hours of cleaning on their own in the place they also live - taking on too much for too long is a recipe for burnout, you don't want burnout. It's just plain bad but you will be a better helping hand long term if you avoid it.
Anyway, you seem like you've got a handle on boundaries by saying no to cigarette money
