I've managed to be a bit "lucky" in that my diabetes has yet to send me to the ER other than when I accidentally OD'ed on insulin and ended up drinking Karo syrup straight to keep my blood sugar's up until I made it to the hospital. (Part of that might be that I didn't have an onset of Type 1 until I was in my 20s.)
Ah, Lantus. I've used that before, but not Solostar. Sounds like the lows are your real problems. I occasionally have days where a 230 would be an improvement.
