I'm on metformin as well Bill, and it works very well. Just so you know, it can have some interesting side affects. Let's just say you may want to know where all bathrooms are whenever you go anywhere as you get used to the medication. If you are susceptible to this side effect, it will regulate itself over time. 'nuff said. :uhyeah:
Just a suggestion, FWIW: Once you start exercising, closely watch your blood sugar before and after working out, so you get a good feel for how exercising affects you. Each person will have her/his own reactions. For me, I need to eat a small carb snack before, work out as hard as I want, then a good protein snack or balanced meal afterwards. As I said before, my blood sugar spikes immediately after workouts, but is much lower within 15-30 minutes of workout, and will remain low for a quite a while.
I think the ADA website is a good starting point and reference. It's great for getting the basic signs of high and low blood sugar and general reference tool (lots of good info), but I wouldn't recommend that be your only resource. Alot of the literature, particularly the older literature, focuses on the scary and worst case scenario (you could lose a foot, go blind, etc.). These are all true, but diabetes, particularly today, is a very livable disease. I think some of the literature out there is meant to be a shock factor as so many people get diagnosed and do nothing to change thier lifestyles. Today, diabetes is very treatable, and (in many cases of type II, particularly if weight is part of the cause) you can reverse the affects with significant focus and exercise.
Based on the impression I've got from you on the forums, you don't suffer fools gladly, and you are determined once you've set a goal. So, you don't need to have the shock treatment for information, and you don't need to be babied along the way. What you need is a good resource of information. You might want to talk to your doctor about meeting with a nutritionist, just for a baseline of information. Then read up and go at it! I'm pulling for ya to be back to the dojo soon and attacking this beast!
Oh, and make sure your wife and dojo mates know the signs of high/low blood sugar as well. If it's a sudden drop or rise, you may not be aware that you are acting loopy or sluggish. It doesn't happen often, but it can happen suddenly, and as I'm sure you know...it's always good to have someone have your back.
