Keep it up guys. For me, in the beginning I had to be strict about ONLY drinking water, I wanted to change my pallet wholly, and I knew allowing other liquid flavors would allow me to cheat a bit. So I have been drinking water for 7 weeks now, not as a challenge, but as a life change. I am not going to say I won't ever have pepsi or a good glass of OJ for the rest of my life, but it will be a rarity (TOM cravings, I often allow a Pepsi, with a snickers bar of course ). Now, it probably was a little easier for me since I had already stopped drinking soda with frequency years ago. Juices were the only thing I had to cut back on.
So I commend you guys, because once you get started you'll wonder why you ever thought it was hard.
