Yes, the abx in pregnancy is to protect the baby. Same for abx while breastfeeding. I am certainly better (or was?) than when I started treatment, so I do believe the abx were effective. What I don't know is if I'm still battling infection, or if it's all the problems that the Lyme CAUSED. These days, I'm more likely to address things piecemeal and figure that the Lyme has wrecked my body and each thing needs to be addressed as its own problem. But, I also suspect some underlying issues like nutritional deficiencies (which goes along with what my LLMD told me about Lyme patients not making good use of nutrients taken in).
In my case, that means first fixing my leaky guy so that I can absorb nutrients properly and detox properly, then tackling my toxin issues (possibly metals & possibly environmental) and then attacking the lyme. In other words, fix the terrain. Now I know this is sort of a chicken and egg thing b/c I'm sure the lyme caused some of the problems and I'm trying to figure out if its a little like trying to fix the damn while its leaking, but at this point, I'm willing to give it a try. I believe that I'm so worn out that I need to start slow & build my body up so that it can fight the lyme itself.
