Fasting.... easy..... what?   I personally have fasted for 18 days, perhaps you could claim I wasn't drinking enough water or needed supliments but I found it anything but easy.  The first few days are quite easy,  I'll give you that.  But after?  The exhaustion was insane,  I felt tired just standing up,  everywhere I went I wanted to just sit down.  I started noticing the smell of food very easily,  found it very difficult to concentrate and even once found myself drooling after daydreaming about chicken noodle sandwiches. From what I knew I thought this was very common,  whenever I see water fasting blogs by day 10 they get the same exhaustion as me.
