Becky,
I would use an elastic bandage, that worked well for me. That way you can tuck the end of the peg out of the way until you need to use it. (it does not snag on stuff that way). If it is too long you can always cut a portion of it off if is is way to long. You probably want to clear this with your physician, also give it some time to get used to it before you do this.
Geri,
Re vomiting, that I avoided although I came very close a couple of times. This always happened a few days after cisplatin treatment and only for about an hour. NOTE: I only had the small dosages, once I was on carboplatin I did not take anything. I would make sure that you load on meds before the cisplatin especially with the much larger dosage.
