Using teas may help at first because you will experience the satisfaction of taste. However, as your body goes into ketosis you may find that the teas will react differently with you. I would not tea fast for more than just a few days.

Splenda is probably the worst thing you can use while fasting. To make sucralose chlorine molecules replace the hydroxal groups in sucrose. This makes the product more like a pesticide than a food. This product can be stored in body fat, then be released back into the system while fasting when the adipose tissue is broken down. Please do more research on Splenda before continuing. Mercola.com is one excellent source of information and is very user and reader friendly. Just because a product is low or zero calorie does not mean it is safe. Aspartame and Sucralose are both potentially dangerous substances that can cause serious and lasting health problems. In addition, constantly teasing the sweet tooth will cause the body to continuously crave sweets. There is research that says regular use of artificial sweeteners will actually contribute to weight gain (then again so can fasting because of the slow down of the metabolism). Please proceed with caution and educate yourself before embarking on this kind of fast.
