I keep glucose tabs in my car and in my briefcase, I don't really have them on me all the time. Rob, one thing to keep in mind being new to all of this is that you don't want to start rebounding for a low blood sugar before it is actually "low" I know when I first started on insulin and got down to 90 I was about to panic. I would feel shakey and start to think, Oh great! I am dropping too low! and I'd take a bunch of glucose tabs and next thing you know.....I was at 300.
It will feel like you are really low when you aren't really all that low, when you've become used to being high. Try to keep the numbers between 70-130. You may not feel bad when you're BG is at 250....but it's doing a number on your body, and in the long run will lead to nothing but problems.
So.... to sum it all up, try not to treat a low blood sugar until you are having one. But it is also good to be prepared in the event that you do have one, when you are taking insulin or drugs that can cause unpredictable low blood sugars, it's never a bad idea to be prepared to treat that low blood sugar.
Good luck!
