I really hope you figure it out....keep journaling and posting....they are the best clues. Also wanted to say one last thing about zinc...just because you take 100 mgs of zinc gluconate does not mean you are getting 100 mgs of elemental zinc...gluconate, piccolinate etc. are things that the zinc is combined with so for example if you take 100 mgs of zinc gluconate you are only getting about 20 mgs of elemental zinc but the rest is gluconate...hope that sheds some light on the zinc scare:)
below is info from the mayo clinic regarding zinc dosages for different treatments....as you can see the doses can be significantly higher that 100mgs for several months at a time
