I'm really excited about this new insulin pen (well new to me as of today - I've been bugging Sanofi here in Montreal to get with the times).
Mainly my excitment is due to the fact the insulin pen doses in 1/2 unit increments. I've been using the Sanofi ClickSTAR pen for my Lantus, but due to being insulin sensitive, sometimes that extra 1/2 unit can send me over the edge into lows, depending on my activitiy.
I already use a 1/2 unit pen for my NovoRapid (rapid insulin) - and it works out grat for me.
Check out more info on it at this link.
Now using a nifty CGMS along with an insulin pump!!!
