One of my co-workers has been drink three very large bottles of water a day. Inspired me to work on my water drinking as well. I definitely do not drink enough water. I filled my bottle twice today but only emptied it once. My job is getting in the way of this as well. Hard to drink huge amounts of water and then do a 3-4 hour demo. I need to figure this out - I've seen what a difference water can make in the past.
