I'm also a type 1 diabetic. My control is pretty tight though (I use lantis for a basil and a pen) so I didnt have any problems. Its funny how you say the highs are worse than the lows. I guess its just opinion but for me the lows are way worse. When I'm low I have a female dog of a time concentrating and even if I drink juice it takes like 20 min for me to feel better. When I'm high my eyes just get dry and I pee a lot. When I took my test I just ate a little more than normal. I think I was around 190 going into the test. By the time it was break I was at about 120 and had a snack, worked out perfectly. I did worry though about it the night before, blood sugers sometimes are a crap shoot anyways.
