I was really sick, getting sicker and on
4-6 wks, off 4-6 wks. I noticed that
for me, the orange tongue
correlated with how sick I felt (mind you I do/did have other complicating factors not necessarily relevant to the orange tongue theory so I'll spare you).
Long story short- I found a doctor who finally treated me for Lymes with Doxycycline and I low and behold, I got better and consequently--no more orange tongue (it's been a year since treatment).
