As promissed a while ago I am back with news about my last experiments. Levofloxacin + tinidazole didn't seem to help me in the long run, so I decided again to switch to something easier to tolerate. You can see what I'm taking at the end of the message or in my personal statement.
To sum it up, the lack of a total symptom resolution during the previous months brought me down to earth. Something was obviously missing from my treatment regimen. That something is part of my current regimen. No idea what has really helped, but I am 99% healed and quite stable. The big jump came after about 2 weeks of intense but intermittent herx reactions.
