Still playing with my Accu-check

Started doing blood tests yesterday and today and had some interesting results:

16:30 - 3.4 mmol/L: does this mean i was having a hypoglycemic attack? I was feeling very hungry, light-headed, was shaking and irritated.

After dinner round 21:00 - 6.3 - surprised that it's lower than 7!

23:30 - 5.4 - why did it decrease, i wonder...

10:00 - 6.4 - this is my fasting bloog glucose level, so I expected it to be lower. But it wasn't ;-(

16:00 - 5.4 - yey!

23:30 - 7.4 - ouch ;-( but this is not my fasting glucose level, though...
