Hi. I'm a relatively newly diagnosed diabetic (I'm introduced myself in some other forums) and have been on a LC diet since mid November. Here's my question for some of you type 2 diabetics. What's going on with my meter???

I checked this evening before bed and it was 135 -- way above what it normally is (about 100 this time of night) -- I rewashed my hands and tested several more times and it went from 124 to 109 then to 93 then 102 -- what the heck???

I have a wal-mart reli-on meter -- are these things affected by cold? I had taken it with me (I teach a night class), it was inside the building but it was in the seat as I drove back and it was really cold in my car. Or are these that inaccurate? I have read that the post pradial 2 hour tesing is the most accurate (even more that Ha1cs) for measuring BG but are these readings reliable?
