Hi All
New to posting in the Forum. Blood Glucose at bedtime generally 6 to 8 at bedtime and mostly 10 to 12 in morning with no food after bedtime. Blood sugar back to about 8 lunch 6-8 dinner and 6-8 bed. Frustrating getting such large increase over night. Take Humulog prior to each meal and Lantus at night. Vildagliptin at breakfast. Diabetians happy with diet. HBA1C down from 88 to 50 in 6 months. Increase in Lantus the answer? Getting frustrated that behaving and limiting Carbs are still giving high morning readings. Anybody been able to overcome this. If so what did you do? Going to use Libra to see what is going on at night for 2 weeks? Any suggestions?
 
Hi Jumbo - couple of thoughts here, you do firstly realise that Libre readings do not reflect exactly the same as a BG meter - Libre measures interstitial fluid glucose, and the fluid generally lags 10-15 minutes behind blood glucose and secondly Lantus is rather slow to show its true effect and takes approx 3-ish days to show this properly whether you've been using it for years or 5 minutes.

Also Lantus does not drip drip drip into you at a steady rate throughout, it achieves a peak after approx 4 to 5 hours, then comes down to a lower level and gets steadier over another several hours.

The idea of Libre is a good one - but wonder if a fortnight is going to be long enough - presumably this one's on the free trial - but can you afford to invest some money in a few more so that you can try adjusting Lantus if you want/need to and have a play to see what happens? Though you can do it without a Libre - we've had to do it using a BG meter for a good many years, but Libre or a CGM does make it a bit easier.
 
Hi @Jumbo That sounds like the Dawn Phenomenon where your body pumps in glucose early morning ready to start the day. Mine starts around 4am. I have a pump to control mine. You could simply set an alarm to test during the night at various times (not all on one night) to try to see when the rise is happening.
