I use diet alone and don't expect to ever need anything else. If I need exercise to bring BG to normal, I know that I have fallen off my personal "wagon". I like exercise for many other benefits, but NOT for blood sugar control. But, that's another discussion. I've gone into it elsewhere.I'm in the same boat as you are, Clebo. I use diet and exercise only to control my levels. I do take meds for my heart but not for the big D. If I eventually need to take meds or go on insulin, I'll deal with that when the time comes. I'm simply happy to be alive at this point.
