I have fasted from time to time to detox my body and while it's not been fun at the time, the results are worth it. I used to be vegan and would do week-long detoxes a few times a year, at seasonal changes. The first two days I would drink water and freshly prepared juices, mostly carrot, apple and beetroot. Soup would be introduced and then fruit and vegetables. Those first couple of days tended to be tough, featuring headaches and general grumpiness. But by the end my body felt light and clean, and that was the desired result. I know plenty of people who regularly detox for health.
The last time I tried to detox, a few months ago, was a disaster. By the end of the first day I was craving food and took cookbooks with me to read in bed! Normally the first day is okay, the second and third days are hard and unpleasant, but you get through that and things become easier. People say the longer you fast the easier it becomes. I suspect the more 'toxed out' your body is, the harder the experience will be.
I have read a lot of conflicting opinion about the worth of fasting/detoxing and I don't think it's something people should launch themselves into. It's a topic of interest to me.
