3rd day of water fasting, acidic and too week.

Hi, today will be 3rd day of my fasting, Since morning I am feeling too acidic, acid reflex burps and heart burn.

I was only on water with a thin slice of lemon dropped (not squeezed) in my pint. I added lemon slice because I was feeling too much nausea.

I also did Epsom Salt + Sea Salt enema yesterday night.

So far my symptoms are:
- The tongue is coated heavily
- some sensations/lite pain in teeth/jaw.
- feeling very week, I slept almost whole day and night
- Since this morning, to much acid, I am thinking to drink and throw up some water. Is it going to help ?

Please advise, I dont want to take tums, but it is getting bad..


PS: When I was brushing my teeth this morning, I vomited and the acid(transparent water) came out was so strong and acidic that i had severe burning sensation in my food pipe/throat.. I am just concerned, this acid may damage inner walls of my stomach and other organs too.. Is it normal having these symptoms.. please reply

Thanks
