I would agree with your herbalist about
having a hard time at least at first. We all have different combinations of things that just work well for our bodies. If you have been feeling pretty good, I'm not sure you should change that until you get closer to being healed, actually.
Now, I say this as a person who uses only herbs, so I don't say it lightly. I would question why my herbalist is anxious to get me off the abx that were working well for me (unless they weren't, of course). Often times it's the combination of things that we use that helps us the most.
If you are ready to make the move anyway, there are many here that made the move in a smooth manner by slowly lowering the doses of the abx until you are finally taking such a small amount that stopping them won't mean an increase in symptoms.
Are you taking herbs that will help support your immune system too? If not, I would encourage you to talk to your herbalist to get started on some.
And, congratulations on feeling this much better!!!
