Hi, so I'm 32. I never drank until my early 20s, and usually I just have a couple of drinks on weekends with friends. Unfortunately, a couple of times a year for the past few years, I've had an extreme episode. Not quite alcohol poisoning, but so drunk that I browned out memory-wise, and twice blacked out the end of an evening. These incidences were very far apart, like, 6 months or more, over the course of five or 6 years. Last week, I had such an incident and browned out parts of an evening that ended in vomiting up what I'd had to drink. It was on an empty stomach, so I was especially drunk. My question is, could I have caused permanent brain damage from these isolated incidents? I have always felt fine, but after this last incident, I have felt a bit slow and then experienced some vertigo, four days after the incident, with no drinking since. I"m concerned that the vertigo is a result of damage to my motor skills/balance area in my brain. Thanks in advance.
