The key for me is to test my blood sugar as often as possible. This allows me to keep it in the right range and catch it before it goes too far in one direction or another. I think they recommend testing your sugar five times a day. I would recommend ten to fifteen times a day. It's a hassle, but getting your sugar under control is paramount for a diabetic. One way I look at it is that controlling my blood sugar is one of the few things in life I CAN take on, no matter what kind of day I'm having otherwise. The trickiest part of control for me is that I'm a musician who travels a lot and therefore has little control over my schedule and what I eat on the road. If I eat at a restaurant, I eat smaller portions, because restaurant food is generally sweeter and fatter (and thus more caloric) than healthy home cooking. I find that travel does weird things to your blood sugar, so you REALLY have to test a lot when you're on the move. I always carry some candy with me in case I start dropping. I recommend M&M's because they don't get mushy after you've had them for a day or two. I play drums in a rock band, and before performing I get my blood sugar up around 200. After ninety minutes of drumming, my blood sugar is just above normal, and it continues to fall in the hours afterwards. I drink juice during the shows if I feel any need. Testing onstage is nearly impossible, so I err on the high side. I wear a medic alert necklace that says I'm diabetic, and I have an emergency glucagon kit that my bandmates and crew know how to administer if I ever lose consciousness. I always buy extra test strips and insulin before traveling and keep them in my carry on bag.
