Good luck Kelvin.... One day at a time is what I keep trying to instill in everyone around here. It'll work for you two as well.
Hard to give any Chemo advise as every situation gets a different type and mix... and it appears that many react different to treatment. Jen's been hit pretty hard and darn near bed ridden the last 2 weeks, yet a gent going thru the same routine as her has renovated his entire house during his chemo protocol.
The only thing that you can be sure of.. there is no length of life without the protocol, so keep your head high and support her all the way through. You can have your own personal moments when you're away from her.. driving.. where ever. Trust me, those days come regularily and there's no shame in it.
Also great that it's just next door Kevlin... can't beat that stroke of luck!
