Biotin
"I have been taking SHEDAVI hair+ skin+ nails. I'm n my first bottle. I've been having more frequent headaches. I'm not the one the take any analgesic but I've been force to take one to relieve my pain. I also hallucinate a bit I see thing running around my house I know can't be there. I was wondering if anyone had experience the same side effects and should I stop taking it?"
