I was talking to my dietician on the phone today and she was telling me how to clean it and asked if they had given me a syringe. I got absolutely nothing to clean this thing with. She told me that it had to be cleaned everyday. The book they gave me said that I could turn the bolster and clean it. I can not even look at it without my stomach cringing. I have no idea what I am supposed to do with this thing, because no one has told me. The dietician said she would call me right back, but that was 2 hours ago and I am ready to go to bed.
