1. I second the recommendation to use a glucometer. I would get symptomatically hypoglycemic even if my blood sugar is in the normal range when I consumed a pre-ride meal with carbs, since our bodies can actutely sense the RATE of change of blood sugar. If you let it get too high at the ride start, and then you start exercising, exercise will cause a massive translocation of glucose transporters to the plasma membrane, which is a good thing, but if the blood sugar then clears too quickly you will feel hypoglycemic even if you are not.
I just re-read your post, and I did not know this. I do get seriously low upon occasion, but have also noted feeling that way even when I wasn't. In my case I think it is totally related to what/when I eat...and it is difficult to judge when my glucose levels peak. Things have improved, but are still unstable - which is why they started my use of a meter last summer. I have had occasional problems with hypoglycemia since I was at least in my teens.

I guess I need to be more strict about when I test before spinning. I have learned that I can't change ANYTHING in diet or exercise without consequences - and am trying my best to avoid starting medication. My doctor has offered it, but it is currently only one option.

I haven't started riding more than an hour as I am still practicing in parking lots, but I need to get as much of the nutrition thing figured out before I start riding Stella down back roads by myself....

All of the other advice is helpful as well. I picked up some Clif Blocs and will check out Nuun and Vitalyte in the near future. I strongly dislike the taste of Gatorade, even diluted, so that is the last choice in my list. Obviously spinning class, while intense, is of lower duration than a good ride, but this is a start.

Thanks again!
