Every morning and every night I check my blood sugar. Based on those values, I might have to take one Metformin in the morning and some amount of Lantus (insulin) at night. The wonderful news is that since 6/16 I have taken Lantus only 3 times, totaling 53 units, and one Metformin on about 2/3 of the days, for a total of 14 pills. During that time period last year I would have taken 3,780 units of Lantus and 105 Metformin pills. Amazing!
