| I like the suggestions mentioned above and I just wanted to add two others. My blood sugars tend to drop about 8 hours after moderate to intense exercise, and I think this is fairly common (having to do with glycogen replacement back into the muscles I think). Anyway, you may want to keep an eye on your sugars around the 6 to 10 hour post exercise period. Second, if you can get someone to workout with, that can be really helpful in terms of motivation.
On the plus side, exercise seems to make my blood sugars more stable, and it's a good way to handle all that stress you probably get from homework, finals, etc.
