I know everyone likes pumping insulin but to be controversial I felt it was too heavy
I thought it was useful for understanding how to transfer basal insulin amounts into the pump basal rates, but much of what is written in Pumping Insulin is stuff that you should be doing on MDI to maintain good glucose levels.
It's really a very good "Guide to managing Type 1 diabetes" with a lot of advice covering everything from how to adjust basal based on highs and lows, dealing with exercise, stress, time of the month, etc. It helps with modifying carb correction amounts, insulin carb ratios, etc. Just because the name is "Pumping Insulin", it's not really just about that. It's a manual for dealing with T1D.
What everyone, including the NHS forgets is that a pump is just another insulin delivery mechanism, and while using MDI requires injections and has less flexibility around basal insulin levels, the reality is that if you are monitoring yourself properly, you will probably run different basal doses for weekends, activity days, post activity night-time basal, etc. The difference between using MDI and a Pump is really minimal. Just because you can manage a different basal rate for different days on the pump doesn't mean that you can't and shouldn't do it on MDI. That's probably why I found the change over from MDI to pump fairly straightforward.
