BrickBack-I know that when you drink a lot of water, your skin also appears more supple.
It feels smoother and it actually makes you look younger. In addition, when you hydrate your body properly your metabolic rate will increase because your body becomes more efficient and will release waste appropriately.
I also heard that adding a little lemon to your water first thing in the morning will kick start your metabolism and cause you to burn more calories during the day.
If you don't like drinking regular water you can also drink carbonated flavored water. These drinks tend to taste a little like soda, but they will also hydrate your system as well.
