Change is hard, and like you said it's easy to fall into the same old habits. Something that has worked for me is to change something small at first. Maybe redecorate your room a little bit, or always make your bed, or always keep your room clean. Then build off of that. You're in your old city again, but you don't have to go to the places you used to, try a new lunch/dinner/beer spot. You spent 2 years abroad, you have the ability to adventure, and there's probably a ton of new people and experiences awaiting you if you get back off the beaten path in the very city you live.
