I am not sure if anyone has tried this, but a friend of mine told me to use a straw when drinking my water. I have no idea why, but you end up drinking a ton more water each day - at least I do along with other friends I know! I can drink double the amount if I am using a straw.
Anyway, just thought I'd share. For awhile there I would forget to drink enough water which is really bad if you are exercising often, but I have to say this little trick really did work for me.
Blessings,
