Girlie- yes and no. What happens over the course of treatment is that less and less of the Lyme spirochetes choose to reproduce. I think they learn that reproducing will kill them eventually and the ones that are left would rather just live. So they learn that reproducing kills them. After each cycle there are less and less left over, and the ones that are left don't reproduce. So at this point if you switched over to antibiotics that didn't get as good brain penetration, it wouldn't matter since the spirochetes left don't really cause any disease and are kind of the survival ones, they live just to survive but not thrive. For example Zithromax or azithromycin doesn't cross the blood brain barrier at all. Tetracycline I think hardly crosses the brain either. Even rocephin has a hard time crossing the blood brain barrier unless it is inflamed by bacteria and leaky or in an IV dose.
Some people treat only on the days when they may reproduce and start a new cycle as this is when antibiotics really kill them easily.
