Hello, I am a Type 2 diabetic, 65 years old, diagnosed 10 years ago, kept blood sugar reasonably under control with pills until this year, when my doctor prescribed Lantus, which I have been taking for a month now. Suggested starting dose is 10 units at bedtime, doc said I could increase to 20 if necessary. Initial response has been good, numbers are well down compared to pills alone. Readings still increase towards end of day. My question is what is maximum dose and is 20 units the limit? Thanks, Andy
