I was diagnosed with Type II Diabetes in 1992.  After several years of oral medications I was put on Lantus as well.  I take 25 units of Lantus twice a day.  This has worked well for me in the past.  In 2004, I had 1/3 of my pancreas removed (along with my spleen). I now also take NovoLog at each meal.  Until last week, I was also on 1000 mg of Metformin twice a day.  I started developing a reaction to the Metformin so my doctor told me to reduce the Metformin 500 mg twice a day.  He said if the problem persisted to stop the Metformin completely.  I had to stop the Metformin.

My last C-Peptide test was about 2 points/numbers to high to qualify for a pump.

Now my question.  Is there a limit to the number of units of either Lantus or NovoLog that you can safely take?  Since dropping the Metformin, I have had to increase my NovoLog by about 5 to 10 units (from 20 - 25 units).  Even that, more often than not, doesn't seem to be enough.  I went for glucose readings ranging from 70 to 160 with an occasional 200+ to an almost constant 200+.
