Maintenance & long term dosing

As I get closer to my goal weight, I’m starting to think about how to handle maintenance.

I’ve been losing weight successfully on 2.5 mg, but my doctor has prescribed me a 15 mg pen. Now I’m trying to figure out the best approach: Do I just stay on 2.5 mg as long as it keeps working? Or should I drop down to 1.25 mg for maintenance?

The other thing I’m unsure about is the longevity of the pen.

Since I’m using such a small dose from a high-dose pen, it could potentially last 6+ months. I: Store it in the fridge & use a new needle each time.

Questions: Has anyone used a pen over this kind of timeframe? Are there any downsides to using it for months like this? Should I just replace it once the solution looks off (e.g. cloudy), or is there a stricter guideline?
