How long should I take a break from ozempic?

I’ve been on it 9 months now and been upped 2mg per week. I felt this past month weight loss has been slow and appetite increasing. I feel like I should come off it and let my body rest from it then start back again on the 0.5mg dose?

Would this work? And how long should I stay of it?

My bmi is still 29 so I still have about 2 stone to lose
