My habit--All of this is either with an ice cube or just cold tap:
I always have a 12 oz glass when I wake up and get to the kitchen, before my hb egg breakfast.
After I have my cups of coffee to get me kick started for the day (I know I shouldn't be drinking coffee...choose to ignore this one.) I have a 12 oz glass in late morning or just before eating lunch.
I have a 12 oz with lunch.
I have a 12 oz with dinner.
And, for dessert! I have a 12 oz'er.
If I TM I will add another.
Then the obvious...multiple trips to bathroom! What a lovely room this has become. MY DH has this as his Disney decorated room cuz we wouldn't let him come out of the "closet" with his house decorations.
taadaa! - voila (vwä-'lä) - etcetera, etcetera
