Hi There I Have This Friend Who Has These Like

Hi there I have this friend who has these like fits we used to think it was because she was somehow allergic to the marijuana we were smoking but then on another occasion we were drinking and the same thing happened to her. It starts by her like saying she feels dizzy then her eyes roll back and she starts to pass out and looses her balance then she shakes abit then in a few seconds its over and she can't rememmber anything
