I use my son's old baby food jar (from the late 90's; yes, I still have them) to monitor my liquids. Fearful to go over limit, I drink only to take medications now. Hold back from water fountain at the gym. Slowly suck on water iced cubs (limit four) throughout the day.

When out, I take sips from my husband's beverage. Or I plan ahead by not having any other liquids for the day. This is an experiment. I just hope this possibly ridiculously rigorous idea works.
