That sounds very unusual for Neupogen. Bone pain and fatigue are generally the only complaints.
I would guess it's something besides the Neupogen causing the vomiting. You absolutely should ask your oncologist to address your symptoms. It's possible to go through chemo with very little nausea if you find the combination of drugs that works for you. You may need to keep complaining to the oncologist until you get what works.
In the meantime stay on the anti nausea meds you have and don't let up, because it's harder to control once it gets hold. If you have some anxiety meds, they may help with the nausea too.
I hope you can calm the storm tonight and get some relief from the oncologist tomorrow.
