Just to name a couple. This helps clear some of the rhetoric you may find yourself up against. Laying credible science on the table always causes a pause in the most challenging educational discussions regarding the borrelia travesty. But, I've never had a doc turn a copy of the science down yet; and the temperature of the conversation always reaches a turning point when the science is most respectfully presented.
