Zofran pump?

Has anyone else had a zofran pump? I've been deathly sick my whole pregnancy, I'm now 27 weeks and it's just getting a little better due to the pump. I've been in and out of hospitals for weeks at a time, last time I was discharged with a Zofran pump. They put a little needle about the size of the tip of your thump in your chest, belly, thigh or back of your arm and it's constantly pumping zofran into you. And they also send in home nurses to put a new IV in every 3 days so I can do a bag of fluid a day from home. The one in my chest I have to change. So, has anyone else had one of these? if so, how'd you do with poking yourself with a needle?! It hasn't gotten much easier yet but I'm hoping it will. Any other tricks to help with being so sick?
