Can I recommend, next time round, you do a none-religious fast, as I strongly dont agrree with these 'no water fasts', afterall we are essentially 90% water as humans. Im betting you got as low as 45% water, which cant be good for anything.
You need to flush in to flush out, its the same as washing your car, collecting up all the dirty water and washing it with that, you just dont get clean!
This is why you also went into dehydration, youre body was not getting enough, theres no cals in water so its not a fast breaker.
Ive just completed another 36 hour fast after a week away last week eating in restaurants and drinking lots of ales (admitedly, real ales with lots of nutrients, but still!) and i feel really good for it! The euphoria you get at about 20-22 hours is worth the wait in itself!
This will also help your bloating issues, as you will grab onto any liquid you can after a water fast or bought of dehydration
Also, water can swell the stomach, so if you feel hungry, downing a hot drink or pint of water can get you extra milage. If using fasting for slimming, when it does come to the feeding window, just eat slow and small and work up as your stomach is tiny by this point, again this will make it more comfortable.
With all the above, you should have removed all the negatives, meaning fasting can be a lifestyle change opposed to a one off
Good work sticking at it though!
