On max dose 15 mg NO LOSS in 6+ mos!

I am beyond frustrated. I've been a slow loser since the start (started 2.5 beginning of Feb '25), losing aprox .5-1 lb/week give/take. Managed to lose about 34 lbs first 11 mos and even with that I'm convinced the biggest drops were when I had 1) surgery and fever for two weeks so didn't eat anything and 2) first colonoscopy and dropped 6+ lbs that week doing the prep! Now I've been up and down with exact same 3-4 lbs for 6 mos. like maintaining. I am beyond discouraged, worried that since I'm on max dose, there's nowhere to go and this is it for me. I'm not in maintenance - I still have 30-40 more lbs to lose to goal range. Dr has nothing to offer me in terms of advice, even admitted he's not knowledgeable and referred me to a nutritionist or specialist (more $$$).

Has anyone added anything else to kick start their loss or restart it? Right now I'm down 30.5 lbs and only hit 15%. Have had a total of 67 shots. I could live with the slow loss much better than no loss. I'm not doing much differently than the first slow months. Dr titrated me up each dose every 5 weeks since I was barely losing, and the thought was that it takes some people to a while to reach their "magic" dose that kicks things up. Not me. I've been on 15mg for 10 mos, with no loss in past six.
