I am 38 yrs old, trying to improve my health and loose weight. Saw a video online saying to drink 2 gal of water for three days to reset metabolism. I drank the two gal Monday and then next day after I ate my first meal and untill now, I get a big headache with a slight dizzyness feeling as well as becoming very tired. My liver enzymes from blood test yesterday are in 100"s, and I feel a slight pain in my liver area if I put stress on it like sit ups or push ups. Im not sure what is going on after I drank all that water which I stoped the next day.
