Hi, I just started the CGMS last week and things have gone well overall. I had an instance last night where it said "WEAK SIGNAL", but moving my pump closer helped. My problem has been with my meter BG's radically differing from the CGMS readings. My trainer told me to expect discrepancies of up to 20 points, but I've had several that differed by as much as 50 points! I just did a meter BG and it was 241, but my CGMS showed 194...I haven't eaten in 3 hours. I'm trying to not overcorrect my BG's for a few days on my trainer's advice. I realize I need to still rely on meter BG's for my actual numbers, but are large discrepancies like this normal?
