My sugar level has been very high for a long period of time. With a hbac1 of 10.4%. Yes I know it's bad but I'm working on it. In the last two weeks of testing I have woken up with a bg lower than 2.6, pretty much every morning. I take Lantus in the evening and having been injecting 21 units for quite a while and have had no problems until now. I have tried reducing Lantus to 17 units for still wake up hypo. It's getting frustrating, I'm exhausted for work, I can't do my driving lessons, hospital don't seem to care anymore. Any suggestions on what to do with Lantus and why my body's suddenly changed?
