Anyone know how long for garlic herx to stop roughly

I have taken concentrated garlic tablets and it does hit something. It may not necessarily be lyme it has antifungal, antiparasitical, antimicrobial activity............., and yes it hits lyme.
It could be anything, even an allergic reaction to garlic.
You don't sound confident that the lyme has been fully dealt with.
You may need testing to clarify your current health status- if you have limited to funds you can try electro-dermal tests, with a good practitioner you can get reliable results but not results that your doctor will have any respect for. Otherwise you should take your concerns to your doctor.All the best with this.

I used the Dr Zhang Allicin (garlic extract). Dang strong. Def made me herx a lot. If you are herxing too much I would pull back on the garlic, take a day off or reduce dosage. It could also be the combo of the antimicrobials. Doxy alone won't be enough for an established infection though so it is good that you are trying to incorporate multiple antimicrobials.

With effective treatments (this can involve a lot of trial and error, and rotations whenever you plateau) you can def get to remission! one of the keys is also finding the right pace of treatment so that you don't overwhelm yourself with constant herxing.
