lyme disease
"Originally prescribed doxycycline for 14 days for Lyme Disease. There was a 2 year gap before diagnosis/prescription, which apparently makes a big difference in a bad way for long term efficacy.



The first round, I didn't have any adverse effects at all.  Easy to take, no upset stomach or significant light sensitivity.  After the first few doses, I could feel pains I didn't have before shooting through my arms. Was told to expect that as a Jarisch Herxheimer reaction (biotoxins due to bacterial die off).



Prescription was extended to 2 months; at 1 month, symptoms were worse to the point of not being able to walk easily or grip anything heavy.  By the end of 2 months, I was 80% better (though still with lingering symptoms). Effective."
