Started to feel hungry again on 12.5mg.

I’ve been on Mounjaro since September and lost 3 stone so far. When I was on 2.5mg I had food suppression but as I’ve moved up mg I’ve found it gets less and less. I’ve been on 12.5 mg for almost three weeks and I’ve had zero food suppression, it’s literally my own willpower that has kept me eating the same amount of calories. But, I’m hungry! I wake up in the night feeling hungry and where a protein meal replacement shake for breakfast would get me through until tea time, it’s barely getting me to lunch time. I’m starting to wonder if I try another weight loss injection as I’m only losing 1-2lb a month now but I’m still 4 stone overweight. I am exercising 4-5 times a week which is why I think I’m losing anything.

What do I do? Carry on? Or try Ozempic or alternative?
