Reddit reviews Pumping Insulin: Everything You Need for Success on an Insulin Pump

Reading Pumping Insulin would be a decent starting point.

Freedom and flexibility are the two big advantages. Also, you only need to stick yourself to deliver insulin every 2-3 days vs multiple times a day. Also, if you're feeling under the weather or going to go work out, you can dial your basal insulin up or down as needed.

The downside is that it requires a bit more work and vigilance on your part (DKA is a more real possibility since you have no long-acting insulin on board), and of course, you have this thing with you almost 24/7. You can safely disconnect for up to an hour or so to shower, swim, or participate other activities that require little or no clothing. :-)

I would suggest getting a book called Pumping Insulin by John Walsh and Ruth Roberts. It's an excellent primer on the ins and outs of using a pump.

Also, whether you decide to use a pump or not, get a continuous glucose monitor (if your insurance will cover it!) They are the absolute best for keeping abreast of what's going on inside you.

In case you haven't already ordered it, there's a new edition of the book here

Not sure how much has changed between editions.
