My body has been a bit of a tart over the past few years. I never used to pass out at anything but a few years ago it started when I broke my hand, I was walking home and my body went into pass out mode so I had to keep putting my legs above my head so I didn't pass out. Then recently since I've been cutting gashes out my shins, ill sit down then go into pass out mode so I have to get on the Redbull quick. The same happened recently when I went to get my tongue pierced, after I got it done I stood up then quite quickly had to sit down again and then get a dose of Rebull. I don't see why I'm passing out, would it just be a lack of sugar or is it just that my body is a bit of a tart to pain?
