acne
"So I've been taking 100mg for a week now. My skin has been noticeably less oily and I've had no new breakouts. However, yesterday I noticed a tingling feeling in my back that last for a few hours then subsided. I toook it today and in about 30mins I started experiencing that tingling feeling in my back again. Think I'm going to stop. I'd rather deal with the oil and acne than experience this tingling feeling."
