I got an email (maybe spam) who knows in response to my Youtube calf twitching video from a guy who reckons he had the same problem along with fatigue cramps and tingling. He claims to have been cured completely by changing his drinking water and using a water Ioniser and certain lifestyle changes but thinks the main reason was the benefit of the water Ioniser.Very expensive these things so does anyone here have or used one ? or whats the consensus. Was thinking of sending an email to ask if it would help the condition we have Just sales pitches?
