low sugar

[Guest guest]

I can't seem to tell when my sugar is low.

for instance, today for lunch I had a hamburger and french fries.

I took 7 units of insulin. at 6 p.m. my wife took my sugar and it was 55.

I felt perfectly normal. Several times my sugar has been in the sixties

and fifties, but I don't ever feel any differently. I don'tknow why I

can't detect when my sugar is low since it seems everyone else can.

Is there any explanation for this?

Thanks for any comments. Dave
