i just ended my 12th day of water-only fast and i feel great.
i have so much energy, no hunger and clear mind.

i also tried dry fast (no water) for 4 days (day 3-6), it was ok but i felt a bit weak compared to the water fast.

i can only recommend fasting, but fast only as long as you feel good,
it’s both mind and body exercise, you have to start small!
