Tirz and Cagri Newbie

I have been on Zep (Tirz) for 2.5 years. I lost nothing after the first year and it just keeps my binge eating disorder at bay. I really would like to lose another 20-30 and do strength training and cardio 4 times a week. I don't eat a ton but so many cravings have come back and with my history of BED - I am looking to add Cagri. I am currently on the max dose of zepbound (15mg) and have been for about 2 years. Do I just start at the lowest dose recommended which is .25?
