"i was prescribed this a few months ago, i took the first day&#039;s pills and had a horrendous headache, but i&#039;d taken many medications before it and had pretty similar experiences and the side effects usually dropped after a week or two. so i kept at it with this stuff for another 2 1/2 weeks, and still the same headaches. so i stopped taking it, i didn&#039;t notice a change in my skin either. maybe i&#039;m just sensitive to this."
