Hi,
I had surgery first, then chemo and radiation. I am fortunate to work from home, but my job is mentally taxing, so I was concerned but determined to try.
What worked for me was going on intermittent FMLA, and I ended up being able to work throughout treatment with minimal downtime.
Chemo was AC-T. I requested Wednesday as my infusion day because I felt okay for the first couple of days, then crashed on the weekend. This schedule worked very well during AC. The Taxol didn't bother me at all, and radiation was easy. I was never too sick to work, and my oncologist made sure that my symptoms were managed very well.
Brain fog is no joke, and I had to be very careful with my work. In retrospect (a year later) I'm amazed that I pulled it off, but I also realize that work saved me. It kept me busy and gave me something to focus on, distracting me from my cancer and the treatments that I thought would never end.
I hope this answers some of your questions, but please feel free to reach out if you need more information. I wish you well.
