I will not have the surgery till July 3rd, but so far in just going from 296 to 273 lbs,, I have had to change my diabetic type 2 medications three times. Which included reducing Toujeo injections to zero, and no longer taking Januvia. A few years ago, I lost weight using a protein shake diet, and within a matter of a few months, I was completely free of not only the diabetic meds., but also all medications, and was able to maintain for the next five years. My reason for the surgery is more about eliminating the meds than anything else.
I think you're really going to be surprised how overall your health will improve. Best of luck!
