Is it normal? 1mg vs 0,25mg

I was wondering if anybody here experienced the same thing. I started my journey on October 3th 2025 at 0,25mg. I lost 20 lbs the first 6-7 weeks and kept on that dose for 8 weeks. A few weeks before the Holidays I went up to 0,5mg for two months and I gained 5-6 lbs back. I had the food noise back which was gone with the 0,25mg… I had my first 1mg injection yesterday and I felt the hunger just like with the 0,50mg dose and also the food noise is back… what’s happening?! Anyone went trough something like that? Is the medication stopped working for me? I still have 50 lbs to loose to feel better (SW 278, CW: 261 lbs) I’m a 45 year old woman.

Thanks for your inputs!
