I was on it for about 40+ years until December 2017. Personally I'm finding Basal/Bolus a bit of a nightmare as you need a degree in maths to be able to obtain good control, and yes there is certainly 200% more flexibility on what you eat and when etc, but it's a nightmare for high protein meals etc, I'm still learning on it, I said to myself I'll give it about 12 months and then decide if I'm gonna stay on it of revert back. So lets see.
Sorry for got to say my average time in target on pre-mix was about 65% on the Basal/Bolus it's about 75% and I'm still learning BUT it is about 300% more work on Basal/Bolus.
