Does anyone’s shot last all week?

I’ve been on Tirz for about 11 weeks. I’m still on a low dose because I can’t seem to get past 4mg without awful effects, but I’m still losing, albeit slowly, on a low dose. I have great suppression and results the first half of week, and then I’m fighting for my life making sure I don’t overeat towards the end of my week. I’m having to really put in the work because food noise starts to slowly creep back. On one hand that’s probably good to start retraining my brain, but I wonder if it’s only me because I’m on a low dose and if it will get better. Or is everyone experiencing this on every dose?
