Sure, but nothing is scientific or exact.
I drink two small/"regular" size bottle of water by noon everyday (plus an orange juice if you want to count all liquids) and then usually make a good dent in the pitcher at whatever restaurant I'm eating at during lunch, and am usually teaching without break after that until 7 when I make another large dent in a pitcher of water for dinner (and maybe another bottle afterwards).
On days I run I have en extra few glasses after the run in the morning and after muay thai I have a packet of "electrolytes" or hydration salts in my water.
Tracking of rest won't be as specific or accurate I'm afraid. When I first came here (read: 1-2 month period of time) I would sleep and wake very early (Up by 6:30 whether I wanted to or not with plenty of energy) and has slowly regressed back to my natural state of staying and waking up late 'till I hit the wall of "You MUST be up by NOW for RUN or WORK" and then try and sleep at a reasonable hour before then.
I feel sleep is very, very important and while I don't always get my 7.3 (How many it takes me to get the full REM Cycles **** done usually) I try very hard to.
