Being low too often is JUST as bad as being high too often....that's why if you have a low A1C due to having too many lows, your endo SHOULD be trying to help you find a way to STOP those lows...
I guess I just don't see it that way. I've been able to avoid dangerous lows, but I'm okay with having a 60 once a day and just drinking some juice to rebound. Trust me, I don't TRY to make it happen...I take as little basal insulin as I can without having consistent highs. But personally I think I'm doing myself more of a favor by avoid highs like the plague.
I've never figured out the correct basal rates to never go low, but not go high either...in other words, a basal pattern that causes my blood sugars to be perfect throughout the day. It's either a wee bit too much and I run the occasional low, or not enough and I'm running high all day. I don't seem to have a happy medium. Thus I'd rather lean towards too much basal cause I loathe being high.
I see too many highs as way more dangerous than too many lows. But I only say that b/c I don't have a history of seizures or hospitalizations though. If I did have that history, I'd think my philosophy was stupid too.
