Dear Dave,
Have been a Type I diabetic for 45 years with no major complications. Have been on Lantus for the last 5 years. I also, have been experiencing low blood sugars (between 25 and 40) with no awareness what so ever. My doctor said after being a diabetic for so many years, the low blood suger symptoms "Mask" themselves. This has lead to numerous problems.
Really hope ther is an answer to this problem.
Ed
