DH had "nap day" on his "unplug day". He'd get up, eat a little, nap, get disconnected, nap, shower, nap...by dinner time he was better. Next day he was tired but managed to work 1/2 day.
I will second the drink a lot of liquids...water, flavored water, tea, lemonade, etc. If you are getting OX along with the 5FU, be careful of cold stuff.
Tell your care team of any side effects early so they can help you.
