Yes, and the question lends itself to control (or lack of) by relevant medical "authorities".

I honestly do not trust somebody with a doctor license who I talked to for 7 minutes out of 259200 minutes (6 months).

For example, when I went on a camping trip, I got bit by 15 ticks. After I got back, went to doc for 15 day doxycyclene, gold standard. And its cheap, like $15. NOPE, fucker wanted the ticks in a bag to grind up and waste a $400 Lyme test. And that test is only 60% accurate, tons of false negatives.

If I could have, I would have bought doxy, scaled it to my weight, and did the 15 day run.

But nope. I ended up getting the second recommended, amoxicilian as "fish antibiotics".
