7.5 not feeling it?

Hope you all had a great Thanksgiving. I was on 5 mg for three months. It was great until it stopped working went up to 7.5 2 weeks ago and I don’t feel anything. What’s the deal? Does this happen to people . Was so looking forward to not wanting dessert at Thanksgiving lol. Any tips? Like would it help to wait eight or nine days to do the next shot or what do you think?
