                        I read your message re quinine with much interest.  I also get a lot of muscle spasms.  What do you mean by tonic water?  Is it sold as quinine in the supermarket or drugstore?  Is there a certain brand I should look for.  I really would like to try it.  It sounds so simple.  Would appreciate your reply.  Thanks Marge
