today is day 6 of my water fast. I went from 212.5 to 196. i couldn't fall asleep all night because of this uncomfortable feeling in the middle of my chest that feels like a tightening sensation. Last night I drank some water and acid came back up my throat and went into my mouth. At night, it started in my throat then went down to my chest. I am wondering why this is happening. I don't want to break my fast. I would like for anyone who has experience about this and what has worked for them. is it due to electrolyte imbalance? or is it part of the detox process? I am in my fasting zone and I don't want to break my fast because for me I have come a long way and would like to see what a longer fast has entailed for me.
