When I was first diagnosed, I was quickly on a basal/bolus regime and needed both Lantus and NovoRapid. I think it was about 10 units of Lantus and what felt like a random dose of NovoRapid: I was not told about carb counting for the first 5 years so took about 4 units for a meal which I increased if the meal was big a decreases if the meal was small.
My honeymoon period lasted a couple of years after which I saw my insulin requirements increase ... it was a slow rise and probably resulted in another 50% insulin compared to when I started.
