I took this for 10 days and my symptoms almost completely dissapeared. I took 1g morning and night. I also got some kind of yellow color on my throat. Maybe the dosis was too high but that can be modified. My problems almost dissappeared but the treatment was only for 10 days so it was probably too short. Going to see my lyme doctor again. This is the only thing that has helped me in the 8� years I've had this ****. I also removed titanium from my mouth at the same time and that is why the doctor gave me 10 days of this antibiotic. It was amazing to feel like myself for 2-3 weeks.
