I pass out sometimes for unknown reasons doctors are still trying to figure out.

Sad to hear this and I sincerely hope that a solution is found pretty soon.

A similar thing has been happening to my old man for about 5 years now and the doctors presumptively mentioned something about his heart's pacemaker. He was supposed to do a surgery in which an electronic pacemaker would be implanted in his body but opted to go the natural medicine way (the doctors were not really convincing in their judgment). We have been managing the situation with natural medicines since then and he's been fine so far. Can't remember the last time he passed out.
