I took Tetracycline on a daily basis from age 13 - 17. Prescribed by my dermatologist for the treatment of acne.
He promised my skin would clear up by the time I was 25. Forty years later I'm still waiting.
I’ve found solutions to many issues i have by running experiments on myself based on risk trade analysis. I’ve found Dr. Berg to be a straightforward person, who usually references relevant studies to back his suggestions on solutions. You can usually look up the studies in the show notes and do your own homework. Hope you find this useful.
