If you have any swelling of your feet, ankles, legs, arms, fingers, eyelids or excessive diarrhea you must stop all salt for 2 to 3 days, just drink the water. The exception to this would be swelling from an injury/accident. Note: Too much salt can cause diarrhea.
Then begin taking the salt again, but add it back slowly. You should use no more than
1/8 tsp ( ¾ g ) of salt per 16 oz ( ½ litre ) of water.
Dr. Batman says drinking plain water by itself will flush out all the extra salt the body was holding in the cells and help clean out the system. The water will run through you very quickly pulling very important minerals from the body. It is suggested you take a multi-vitamin with all three main meals to replace what minerals might have been pulled out.
When the swelling is gone, you can restart the program of drinking half your body weight in ounces of water. This time however, you will take it in small amounts throughout the day, slowly increasing the amount of water until up to half your weight in ounces of water has been reached. Also start taking the salt with the water.
