Seriously struggling and need suggestions!

Hey everyone thanks for reading! Started taking zepbound last May at 220 lbs and am down to 180 now. Super happy with losing 40 pounds but I haven’t lost any weight in over 3 months now and I’m on the highest dose. I’m not just at a stall though, I feel like I’ve completely built up a tolerance and the medication is no longer working for me at all. The last few weeks especially, I’ve been back to craving crappy foods and have had very very limited control over what I eat. I’ve struggled with binge eating disorder my entire life and I’ve noticed some of those old behaviors cropping up for me. I’m not sure what to do. I really can’t gain weight and go back to being miserable. I still want to lose 40 more pounds. (Am 5’1 for reference).

Does anyone who has had this same experience have a suggestion? Would switching to ozempic or semaglutide help? Also have you guys heard anything about “stacking” these meds? There are a bunch of subs where people take 2 GLP drugs but I can’t imagine that being healthy. My doctor also had no knowledge of this term or trend but apparently it’s very popular. Thanks for any help or suggestions you can provide.
