Temporary Blindness/Faint

I have a very close friends who refuses to seek a doctors help, but I'm very worried about her. Recently (usually after a night involving alcohol) she'll wake up very early and begin to feel dizzy and proceed to be temporarily blind for a few minutes. This has happened to her 2 times before. She drinks most weekends and is a very unhealthy eater, and is extremely thin despite a very greasy diet. Any information about what might be wrong with her would be greatly appreciated. Thank you.

It's all from being an alcoholic! Needs to see an MD

Your friend is on a death trip. As gymdandee suggested, she needs to stop drinking and see a medical doctor. Tell her that there are worse things then dying.  If she doesn't get her act in order she could end up a blind quadraplegic.
