I made to switch from MDIs to a Medtronic pump almost 4 years ago. I do not have a CGM as my insurance at the time wouldn't cover it. My control is much tighter on a pump and I enjoy the freedom of not being tied down to eating at certain times, which I need being a mom and in nursing school. You also have to be willing to test more and get good at counting carbs. That being said, being on a pump has its disadvantages too. I can't tell you how many times my tubing got caught on my daughter's foot when she was a baby or on a doorknob during clinical and got ripped out. If you don't have your insulin and syringes or a new site on you, you're SOL. I've had that happen too. All in all, I'd much rather be on my pump than injections.
