If you are running out of the spew pills, ring oncology and they will organise a script for you. Do not go without, just don't. It sounds like you are coping really well, so give yourself the best chance you can of being comfortable.
If, and it is an 'if' you end up getting bone pain from the Neulasta shot it will probably be on Sunday. Don't muck around with it, take what ever pain relief you can and if you are still in trouble on Monday, go back to the hospital and demand something stronger. Suffering is for saints, no need for the rest of us to put up with it.
Reactions to the colony booster (it stimulates your bone marrow to make more white cells) vary greatly; at least your nurse gave you a heads up. Some people have a bit of discomfort, for others (like me) it was a totally body toothache and I needed to pull out the big guns --targin is good-- until I found out about taking Claratyne to help reduce the pain. The theory is the pain is bone odema and the antihistamine reduces it. The key is starting the day before chemo and continuing for a week. Every chance you won't have any trouble, but if you do,, ask your oncologist if you can try it next round. It's standard practice in many clinics and others poo poo it and say it doesn't work. I had chemo twice in ten years, it worked for me.
Keep up the good work! Mxx
