Everyone here has such good advice. Thanks for reminding me of things I need to be doing as well! I have to agree with pretty much everything. I always carry my meter with me and there are always glucose tablets in my case. I don't know everything to do with Type II. I have Type I and use an insulin pump.
As someone said, usually if you are going low and you treat it, you will have to wait. I usually feel really funny after my blood sugar has gone low. Be sure to not overtreat a low. Fifteen grams of carbs is all you need to bring it up. I used to drink a glass of juice and then eat something, after all that, I had what I like to call a blood sugar hangover.
Another thing is to be careful not to guess when you are low and guess when you are running high. I have been diabetic for almost 17 years now and through different times in my life, things have changed. I guess it is just what your body does. For a long time my lows were very pronounced and obvious that I was low. Then when I got older I would feel like my blood sugar was 40, then I would check it and it would be 240 or higher. If you sugar has been running high for a day or so, when it get back to normal, it might feel like a low.
Carb counting is another thing that I'm sure the doctors have talked to you about. Learning how many carbs are in things and how many carbs you eat is pretty big. When I started using the pump I learned all about carb counting. It helps me to be a little bit "normal". I can adjust how much insulin I take to eat a big meal or a small meal or a piece of cake or anything in moderation. Like I said before, I'm not sure how that is incorporated into treating Type II.
Lastly, I would say remember that everything and I do mean everything effects your blood sugar. If you are stressed, it will probably go up. If you are sick, it will go up. If you are taking any kind of medication for anything, it might make it go up or down. If you are tired, it will effect it. I recently had pneumonia, the medication in the breathing treatments made my blood sugars run really high. So be careful and know that is what might be happening.
Sorry that everyone here has to deal with this awful disease. I have my days, months, years of really hating it, which I'm sure everyone here has. Know that it is normal to be frustrated and even a little depressed.
Good luck!
