Random fainting issues
soo for prett much my whole life or atleast as far back as I can rember its been happening anyways ill be walking along and randomly ill like faint for a second but in the process of the collapsing everything goes dark and weak and just well faint now when I wen tot the doc he said drink more water eat more salt, now im wonderin if ny of you guys have knowledge on this or even a name so I can effectively research this, as I cant afford to go to the doctor anymore as I need to save for school and the like, the doctor was a heart doctor if that helps, but yea any info you have pertaining to the subject that is actually about it not some smar ass thing... would be greatly appreaciated!
