Sometimes I wonder how much I should trust my meter, versus just going on "diabetes instinct" based on how I feel. I've had times where I've done something completely illogical like eating without bolusing or not corrected a low because I "felt" like I was going up and it's turned out okay. On the other hand, I've had times where it didn't work out well at all, which is obviously why I keep testing!
I woke up this morning at 5.3 mmol/L (95 mg/dl) which is good. Ate the breakfast I eat every morning. Two and a half hours later I was 9.5 (171) which annoyed me that I hadn't checked sooner. If there's a time after meals I'll end up high it'll be breakfast, so I corrected it and went on.
About an hour later I wanted lunch so I tested to see if I was low enough to eat and ... 3.6 (65 mg/dl). Now I have been having problems with highs lately and hardly any lows so I was surprised I'd drop so much in under an hour. So I tested again and got 6.0 (108). Now utterly confused about which number to trust I tested again and got 4.9 (88).
So now I have no idea whether I should eat a few Skittles, or subtract the insulin on board from my lunch bolus, or what. Since I've been having problems with highs I'll probably just bolus normally and then just keep an eye out for going low.
But just, argh. Diabetes is enough of a guessing game without having to guess about which reading your meter gave you is accurate! (I'm also going to pick up some control solution at the pharmacy to check my meter, hopefully it won't be too expensive ...)
