Hi, keeponmovin,

I'm not sure I understand your question. You don't know if you actually fell?

Where were you when you woke up? If you'd fallen, you would almost certainly have been on the ground or close to it. And the chances are that some part of you might have been hurt to the point where you'd notice it, even if it was just a grazed knee.

But whether or not you fell, blacking out is something to be concerned about. The first thing you need to do is look into any medicines and supplements you might be taking. Some of them can have serious side effects.

But it also sounds as if all you'd had to eat that day was a bit of chocolate, and at 6:45 PM you fainted or blacked out. As Lara said, going without food for such a long time isn't something many people can get away with even though there are people who intentionally fast.

A regular schedule for meals and sleeping can work wonders, particularly if you're making sure that you're getting the foods your body needs.

Have you had a physical exam recently? You might want to be checked to be sure you don't have some problem causing loss of consciousness.
