#1) Balance is everything. Too much of anything can be bad for you. As long as your internal organs and blood pressure are okay then salt should not be a problem, but if you are craving large quantities of it, as well as other chemicals then you should have a physical from your doctor.
#2) You are committing a slow suicide. This stuff is poison. Get off of it ASAP. If you want medical studies I will do a search for you. If God didn't make it you shouldn't be eating it.
#3) As long as your internal organs are functioning okay you can drink as much water as you need. This is not a concern unless you are an athlete who might risk electrolyte imbalance/depletion. I have seen only one patient with water intoxication and that was years ago when I was a new nurse. He was mentally ill and a psych patient.
#4) Keep doing this and eat lots of fruits and vegetables.
#5)I don't know anything about this diet but if you are feeling poorly it is not good for you. See your doctor, get a complete physical, then ask for a referral to a nutritionist. He or she can work with you to develop a healthy eating routine which will allow you to get your nutritional requirements and lose weight. Finally, move your body. Burn more calories than you take in and you will lose weight. Plus, you will feel better.
I appreciate your comments. I'm curious about the electrolyte imbalance. What is that?
