That's why I went amoxycillan. I can buy medical grade as "fish antibiotics".
Alpha-gal wasn't prevalent then. It was primarily Lyme and rocky mountain spotted fever. Doxy and amox is the gold/silver standard for both.
I don't need a fucking doctor to tell me I was bitten by 15 ticks. I removed them myself with a tick puller. I don't need to he told that I probably got a disease from at least 1 of them. So yeah, its either going to cure the infection before it starts up, or is a prophylactic to prevent it.
And in more sane countries, I can go in a pharmacy, tell the pharmacist and reasonablely and cheaply treat myself. US? Not so much.
But, I can smoke delta8, tobacco, and drink until my lungs and liver give out. But how dare I take some antibiotics when I need them.
You make a good argument for expanded use for true "OTC" meds (Over the Counter - as in can't be sold on the shelf in bulk but has to be given by an actual Pharmacist).
