I only have the pump, but I do not like to lay on the infusion set at all. It doesn’t hurt (usually), I just don’t lay on it. OK, now that I write this, I’m really not sure why. I think that somehow I got the idea that the site will last longer if I didn’t lay on it.
When I started on the pump, I had poor insurance coverage and I tried to make sites last as long as possible (6-8 days). I guess that got me in the habit.
I toss a lot in my sleep, but I must always start by sleeping on the side where my infusion set is not.
If I have a painful site, then I clip the pump to my pyjama pants in such a way so that I won’t roll into that position. Even when I am unconscious, I do not like to lay on my pump!
