Hi TIFFY . . .

(or, I guess, welcome-back might be more in order.) Anyway, you have definitely taken the very wise first-step on the winding road to better health and fitness and that is what really matters.
I'm a 'little' older than you (as a matter of fact, I could be your grandmother

) and I've been a Type II Diabetic for better than 15 years and I do use insulin as well as a few other meds. Just wanted to let you know that there is a special Diabetes-related forum on this board that you might want to check out. Sometimes it can really help to talk with others that have first-hand experience with the same kind of problems you are facing.
Here's a link . . .
CLICK HERE FOR "DIABETES SUPPORT" FORUM . . . feel free to pop-in and join us.
Have a great moving and shaking kind of day. We'll all be looking forward to seeing 'less' of you, 'more' often in the future.
