Almost Fainting

Quite a few times a day, it happens to me that I nearly faint. My vision blurs completely, I feel really dizzy, nearly fall and I can be like that for up to a minute... It happens quite often. Also I feel... Floatey... Yep, I m asking for any advice regarding that and how to fix it. I m not sure if it had to do with sleep, as even today, after two days of sleeping pills and full nights if sleep, it s happening... Thank you for reading
