A Flagyl rhythm is emerging. Maybe I was not mentally clear enough to see it before or maybe it was not there. Maybe it is the stage of recovery or the addition of Azithromycin and NAC a couple of months ago. My 14th pulse of Flagyl ended 13 days ago but my body is telling me to do it again. I have become aware the last few months of not a tingling but a "shimmeriing, glowing" after about 12 days post Flagyl. I feel REALLY good after the fog wears off (about 4 or 5 days after finishing Flagyl) then there is a buildup, very subtle at first, now clamoring, of -what?. I woke at 5 am wondering if I could take 1 dose of Flagyl of 500mg. (in the US we have 250 and 500mg) per day every day or if I might just begin a week early. My walking is not as good either- not bad, but it was better than ever 12 days ago.
