Hello Mamas Girl,
I think it is quite normal for the vast majority of water fasters, starting out on their fasting experiences, to suffer from withdrawals from either tea, coffee, tobacco, alcohol and other stimulants, but with each subsequent fast (and a cleaner body) these symptoms are minimized or just do not occur any more. This is of course unless you resort back to old eating and drinking habits!!!
has this to say about headaches and other symptoms in the early stages of a fast..............
"The first two days of the fast are usually the hardest, due (1) to the persistence of the demand for food, and (2) to the sudden withdrawal of the accustomed stimulation. Headache, dizziness upon arising, spots before the eyes, nausea, vomiting and gnawing, or an "all-gone" sensation in the stomach, are the chief elements of discomfort during the first few days of the fast. These symptoms are largely the result of the withdrawal of coffee, tea, tobacco, condiments and stimulating foods. Fat people and "good livers," suffer most in these respects. As a general rule, it may be set down that the more marked these symptoms are during the early days of the fast, the sooner the fast will accomplish the desired results."....
