I am about to have my last of four dose dense AC Chemo @Wu57 and while I have had side effects like runny nose, acid throat, fatigue, constipation, watery eyes, baldness :# I have also been pretty well. I credit a lot of this to walking every day, up to 30+k a week with my partner. We both find it is good for our mental and physical health.
Good luck with your chemo and your job. Its doable but be gentle with yourself. I work from home so I can adjust my schedule and have no travel time.
I would make sure that you talk to them about adjusting things and maybe going part time to start with until you see how you cope with chemo. You are the main priority in all this and trying to keep up and cope with it all puts a lot of pressure on you which you don't need.
p.s. Coloxyl tablets are great for avoiding constipation but start early, I only found out later that the injection you get on the day after is a culprit. And I took claratyne that I'd read online about to avoid bone pain from injection.
