Congrats on the weight loss, and you can lose that final 18 lbs!
I am now down just under 65 lbs since starting my low-carb/keto diet early last year (after learning I was Diabetic), and still loosing slowly but surely.
I just had to get it through my head that there were certain foods I was going to have to give up basically for life. The benefits are worth it though. Going low-carb/keto (moderate protein), has allowed me to get my numbers back in check and off of the diabetes meds (Metformin) which were causing severe pain in my knees constantly. I feel tons better and am a lot more active like I was when I was younger!
