About Us GMFA Blackouts Sometimes you wake up after a heavy night and you can’t remember a thing about it. If you’ve been to a chill out, sex party or sauna and you blacked out or can’t remember what happened, you might want to seek help, especially if you think you may have put yourself at risk of getting HIV or had sex you didn’t consent to.
