I'd try to look at it from the other direction; if there's not much else in your life (yet) then it's possible to become "addicted" to just about anything that's comforting? I'm addicted to clean sheets and warm showers myself, LOL.

There isn't anything particularly good or bad; there's "habit" and sometimes, addiction because things get out of balance. If you're worried or bothered by your routine, experiment with varying it and/or talk to your doctor about using less of the med or tapering off some, etc.
