I am unclear of this I drink about 1 gallon to 2 gallons a day. Some people have told me Its good, The more water I have in me the less fat I have in me. And some have said its bad, That it makes me heavier and It makes it harder to do cardio and Jogg. So Is it good or bad? Should I drink Less? Maybe more? I can drink 1 and a half gallons with no problem I love water. Always have.
