That sounds very scary and a great reason to quit!
I'm sorry that you lost your father at a young age. I can't imagine what that felt like.
I'm no doctor but for that incident you described, did they rule out dehydration? What was the weather like? How long were you outside? Did you drink any other fluids?
As far as night sweats, that could be related to your binge drinking. Look up kindling. It's also very possible that those side effects can get worse.
