I've also been injecting for quite a lot of years now, and have *just* started on a pump (almost a week ago now

)
Mine is an omnipod and I have to say that so far, I LOVE it.
I currently have it on the back of my arm and honestly, 90% of the time, I don't notice it's there at all. I can feel the cannula when I actually bolus, but that's pretty much it.
I am also a pretty messy sleeper, but, again, I've barely even noticed it in the night.
i chose the omnipod because I do quite a lot of (non contact) sport and training, so I wanted something that was waterproof and wouldn't get in the way. So far, it is definitely both of those things
