Hey just wondering what sort of reactions/herxing any of you have experienced while on Doxy. I've been on it for 6 days now and I am extraordinarily exhausted. No nausea, fevers, etc-- just so tired with average muscle aches and weakness. This is an experimental treatment b/c all of my lyme tests have been negative. I hope I didn't take this for nothing, I hope the tired feeling I have now is b/c the toxins are dying off, lyme related or not.
