I got diagnosed with "the 'betes". Decided not to take meds. I fast all the time. Yeah, I get wobbly, as you say, but then I test. If my GL is high, I know it's just my body being a spoiled little child, and I basically tell it to eat the glucose that's already in my blood. The wobbly's go away shortly after that...it's all a big bluff....and then I feel fine. If my glucose is normal, I plan on eating a meal at a normal time. If it's low, I eat something I actually like. There's no way I'm going to waste a good low-glucose count on those drug-store glucose tablets. I'll eat some nice chocolate, or a sweet, or some popcorn or something. If I'm high, I run or do some work. ...But usually, if I'm low, I'll just let it go until the next meal. Since I don't have drugs artificially dropping my levels, I have a much more predictable, and stable glucose range. I've never passed out, and never had it go any lower than the high 70's. I also watch my diet, and take several beneficial supplements. I DO need to get myself some blood tests though (as in, without a doctor). You see, I'm stubborn on many more things than trumpet lessons.
