Moving up to 5mg - dr lazy?

So, insurance won't renew my 2.5mg and are forcing me to move up to 5mg unless the dr sends in a PLA (personal level auth) - they already did the PA. Dr's office said, well, we'll just move you up to 5. This is my first month of zepbound, I went from 232 to 215 in a little under 4 weeks. I kind of would like to keep this dosage longer, but I guess I'm ... movin' on up.
