If I was you I would drink More Water. Lemon is a diretic [sp] so it sucks the water out of you so you have to replace it, if you aren't eliminating much then I would say your body needs more. Just keep drinking, LOTS. I buy about 40 lemons at a time and keep them in the fridge, they seem to last forever but I have wondered about freezing the juice as you say. I think it would be great in ice cube size and just plunk one into your drink. Hope someone tells us if it's okay. Great to hear that you are on day 6, it's a wonderful feeling isn't it? Keep it up.
