I DID drink more water than I usually do and I was more aware of my water consumption. Here's how it went:
I drank a whole gallon or more for the whole first week and probably half of the second week, then I fell off the wagon the second weekend and had a hard time getting back to it. When I did manage to drink a whole gallon, my feet didn't hurt as much when I woke up the next morning. When I put my weight on my feet first thing in the morning, I have some pretty intense pain for the first 10 minutes or so. I'm sure this is from years of torturing them and forcing them in shoes that didn't fit properly or shoes with heels too high. When I'm drinking enough water like I should, this is a much more manageable pain. This has been incentive enough to make the effort to drink more water!
The 'small' jug here holds half a gallon of ice cold liquids, but I've been carrying the giant Squatch mug here that hold a whopping THREE quarts. My goal is to get into a habit of drinking two of the three quart mugs a day, bringing me up to a gallon and a half a day. I don't work in the heat or sweat very much so I'm not concerned about washing away all of my electrolytes. I've read that you should drink one ounce for every pound you weigh, so I'd be pretty close with my 192 oz per day average. I have yet to actually drink two whole mugs in a day, but I'm finishing one and starting a second most days. I really do feel better now that I'm drinking more water, you should try it!
Warning: my face did break out more for about a week, I assume it's because I was flushing out toxins. If you up your water intake, don't be surprised if this happens. It did clear up quickly. Now I'm only noticing breakouts if I don't drink enough water for a couple days.
How much water do you drink?
