Question and update on my fasting.

I am on my 7th day of water only fasting and also my last day. I am going to start juicing as a re-feeding and then veggie soup etc.
Today I feel better. The last 3 days was terrible. I had this dreadful feeling on the lower part of my esophagus not pain or anything like that but just dreadful plus the nausea and I had to spit now and then. But when I went to bed I felt better all the dreadful felling dissipated but I cannot sleep all day I got to work for living.
One thing I observed different from my previous fasts is that when my sinus cleans what comes from my nose and through the throat is pure salt. Fellow fasters! Please shade some light on this.

Thank you!
