My doctor wants to increase my dose but I feel great at 0.5mg

Started on 0.25mg, moved to 0.5mg after a month, and honestly the appetite suppression has been perfect at this dose. I'm losing about 1 lb a week and the side effects are barely there.

My doctor wants to bump me to 1.0mg at next refill because that's the standard titration schedule. But why mess with what's working? Has anyone successfully stayed on a lower dose long term? Want to have an informed conversation at my next appointment.
