It's great to see all the positive responses about starting pumping, but remember everyone is different. You may need some time off. I took 2 days off and it wasn't enough and had to take more. This was mainly because my training was very brief and poor quality, and because of cannula problems, which 6 weeks in, I still haven't resolved. That plus I was fighting off a cold, and suffering hormonal insulin resistance...The timing couldn't have been worse! I am getting there, though.
The other issue I was not prepared for was the emotional impact. Going on the pump brought back the trauma of my diagnosis (which was extremely traumatic). That plus living alone, without support, and a lot of fear - I felt I had to learn to fly a plane from scratch, while flying it. Thank god for the 24 hour helpline!
My advice would be: be nice to yourself, get as much support as you can, and don't beat yourself up if getting your doses right is tough - it will be - or if you find it hard, or emotionally draining. You may have an easy ride, and find your initial basals work well and your first type of cannula is the one for you - but we are all different!
Having said all this, on a good day my BGs are amazing, and I know it'll all be worth while in the end. I haven't once considered going back to MDI.
Good luck!
