well, Abby if you want to/are able to keep it in they will let you. personally
I hate having it in at home so I take out almost every time unless the time in between infusions is short. They should let you keep it in, they always asked if I wanted it in or out at the end of the infusion when I did it at the infusion clinic. they do serve some food and drinks to keep ya happy although I'm never hungry during it.
hope ya have fun
