Minocycline
"I'm rating this a 6/10 because it was INCREDIBLE for my acne. After a week my skin had never looked so clear in 10 years. It was seriously amazing. But unfortunately it made me unbearably dizzy. I had to stop after two weeks and I was so upset about it but I just could barely function. I've been taking Doxycycline now for a month and it works half as well but doesn't give me any side effects. I'm bummed out about it but it's worth trying in case you don't have the side effects I did."
