A bit late to reply to Eltry now, but I’ve only just seen this thread!
Re driving while on my initial chemo, the simple answer is I didn’t. My wife had to drive me to the hospital and back as I was too weak to drive. It was a few more months before I was back behind the wheel.
Eltry, did you go ahead with your treatment? I would say that you really should go ahead with the initial chemo, MM will get you in the end if you don’t. There are however treatment choices you can make further down the line.
