I went from drinking a gallon of Vodka and 36 diet cokes a day to drinking a minimum of 6 gallons of water a day and then to treat myself after the water is down, I have some sugar free koolaid. It is really amazing though what a difference it made in me ( forget aboutthe Vodka for a second), but I had been drinking a minimum of 18 diet cokes a day since I was 12 and as soon as I kicked that routine, the pounds just flew off! I am so use to water now, that I down 3 gallons before I eat breakfast to start the day. Takes me about a hour to crush through the 3.
