Are you having infections right now? If not, I'm not sure how waiting will make you more sure about them. Believe me, they will be monitoring you very closely. In my case, I missed a couple of treatments because my blood numbers weren't good enough, even though I felt okay and wanted to go through with them.
Afterthought--this thread should be moved somewhere more appropriate than "chit chat."
After-afterthought--I was also very worried about infections. This was mostly from my reading about all the bad things that could happen. I actually bought a new electric razor so I could avoid having to use blades. My oncologist set me straight, and told me just to live as normally as possible, and that my fears were exaggerated. They were. I had no problems with infections, and the chemo went by pretty quickly. You can read about it by clicking the link in my signature.
I sat next to a guy who was having his first session. He was a strong ex-marine. By the time the oncology nurse got through telling him all the side effects--nausea, fatigue, hair loss--that he *might* experience, this strong, powerful guy was ashen and pessimistic. He was crumbling right before my eyes. And he hadn't even had so much as a band-aid put on him yet. Focus on the good chemo will do, and how short a time you'll have to go through it.
It won't be nearly as bad as you're thinking it will be.
Final afterthought, I promise. Get an ipod and get some audio books from audible.com. You'll have several hours of peace and quiet--well, relatively--to listen to them. There are worse ways to spend an afternoon.
