Count me in on the vote for a herx - so sorry you're dealing with this!
You really need to be doing more for detox and you need to be doing everything daily. There are a bunch of easy supplements you could add to your detoxing protocol that can help immensely. Please take a peek at the following link for detoxing ideas and slowly add some:
www.tiredoflyme.com/detox-methods.htmlAlka Seltzer Gold can really help with herxes. In fact, I got to taking it twice daily whether I was herxing or not.
It takes awhile to get ahead of the toxins being produced during treatment but there will eventually come a time that you don't need to detox as much. Truly, everyone benefits from detoxing even when healthy.
And, yes, herxing on abx is confirmation that you are dealing with Lyme and possibly coinfections.
Hope you feel better soon!
