Yep, did did it 5 years ago for 7 days, helped me quit smoking without any NRT or withdrawal symptoms, the hunger pangs for the first few days hid any urge to smoke as urge to eat was greater, after 3/4 day no hunger at all, then came the mental clarity, felt energised and pure. Afterwards drank only fruit juices for first few days and ate only raw fruit and veg for next few weeks.
Regularly do the odd day here and there - planning on another 1 week fast in new year.
Quit smoking, practically cured severe anxiety/depression and overall health.
