Is tonic water harmful ie quinine?

Answer 1

I had leg cramps regularly every night.  I'd leap out of bed from a sound sleep to stand on the offending leg to work it out.  

I now drink about 6 oz (small juice glass) of Tonic Water or Quinine Water found in the supermarket daily.  I drink it before bed.  It completely does the trick.

I do notice, if I fail to drink it the cramps come right back so it doesn't cure them or work for longer than a day.  

It is a  bit bitter on the tongue but you can develope a taste for it after a while and it is rather refreshing.  Try it but I suggest you only drink a small amount.  Seems to work.
