Hi,
As much tap water as you can drink, either warm or refrigerated.
Any sugar free drink.
Skim milk products - nothing full cream - I use "Coffeemate" with my coffee.
Eat as much fruit and raw vegetables as you like and oranges are good thirst quenchers.
I have a liquidiser, which reduces fruit into a smooth liquid drink and I make smoothies, which I recommend to everyone.
My favourite is one apple, one banana and one avocado blended together with 1/4 cup of water to pour the liquid completely out of my liquidiser, into a large cup.
there are many free smoothie recipes on the internet, so copy and paste some of the more popular from the web page into your word processor and save to your hard drive, from where you can see them on your monitor or print them out on your printer.
Buy a juicer, which extracts juice from vegetables, such as Celery, Carrots and fruit, Apples, etc and drink the juices, while throwing away the pulp.
