birth control
"I'm 18 yrs old and I started taking this after the first time I had sex, overall this proscription has proven to be so accurate but I am very big on taking it every day at almost the exact same time(30 mins off but never more than that) 

And I did notice when I first got on it my sex drive went down and I had been really moody. Things that wouldn't normally get to me did but not 6 months in everything is getting regular. Very, very effective!"
