Hi,
Hope you're doing ok. I will try to give you an answer to your question based on my experience, but it can be frustrating because everyone has different experiences. The thing that delays my bad days is the pre-meds that they give me before treatment. I get Zofran for nausea and Decadron (sp?), a powerful steroid that makes feel better than I actually am, until it wears off. These are the pre-meds that I presently get with the Gemzar Abraxane chemo. It was similar, but different brands, that I received with the Folferinox. This, I think, explains my delay of the bad days. Additionally, I have found side effects to be cumulative, where bad days might stretch out a little longer, the more treatments you get. I had dosage lessened to guard against that. I hope is helpful. Best wishes.
