Quinine in injected can cause heart electrical issues yes.......but need to do more research on this one....a can of tonic water has very litttle quinine in it so you may try it It worked for me......this is truely hell I can not understand how you are dealing with it long term.......it really is hell!!!!!!!!!!!!!!!!!! I can't imagine dealing with this long term my two weeks were enough for a lifetime..
