Hey
I've had my pump now for a couple of weeks. My first appointment I did go home with a pump but used saline for nearly a week - this allowed me to get used to the various different settings, iron out some set issues (unfortunately I'm one of those people where I'm now on my 3rd set type) and also just get used to wearing it etc. Even though I wasn't expecting to have to do this for almost a week I actually became really grateful for it.
I've been given a manual that's a bit like a DAFNE guide that I have found really helpful and since starting I'm working closely with my diabetes team uploading my data every 2 days and they are helping me make the tweaks. I don't know if this is because I was pregnant when I started.
I would ask as many questions as you can at the beginning - there's nothing stupid I've found and your team will want this to help you so will be happy to answer anything I'm sure.
Preparation wise - find something you want to wear in bed that you can clip your pump too (although i've heard some people sleep next to theirs, I personally wriggle too much). Be prepared for some 3am testing while you get your basal right.
Partner wise - I've found my hubby and I are both learning together. It's a real learning curve again.
Driving wise - I've not done anything long distant yet but I've not had any issues. Check before you drive, keep treatments on you and I've basically worked in the same way I did when on MDI.
Challenges - when something goes wrong that you are not expecting and you don't immediately know how to sort it (I had a set fail and the shock for me is quite how quickly your blood sugar can rise), I'd also say that whereas before when I had a hypo I knew exactly what to do, how my body would react and could easily think how much insulin I had in me etc. With a pump I'm more wary, especially if i have a late evening hypo but I think this is just a learning curve again.
Will say this though - I am glad I made the change. Not injecting is lovely. Yes it's still hard at the moment and there's a lot of thinking involved but I can see how the benefits will be great. It's a big positive change for me - I hope it will be for you too.
Good luck x
