I've been on tiny doses since June 2017. I've been treating everything, though I started with most of the bartonella protocol.
Back in April, I had to take a break and when I restarted I found I was even more sensitive, so I stayed at lower doses and only 2x day instead of 3x day like I started out. I also never resumed some things - EGCG/Quercetin, cordyceps, red root.
Anyway, I'm taking the looong, slooow route
But . . . lately I've been starting to feel better and actually notice the progress that I've made, which is pretty cool considering how many times I've felt like a hopeless, lost cause over the past year.
All I can say is treat as long as it takes and don't be afraid to try new herbs, supplements, or treatments including addressing issues other than bartonella. The most improvements I've had came after using anti-fungal and anti-parasitic herbs and supplements.
