Alcohol memory loss?

I know this is your average dumb Reddit question but I’ll ask anyway. So in the first 4 months of this year I have gotten drunk 4 nights in a row on 3 separate occasions and because of that people are telling me that I now have lingering brain damage and lost some of my memories. It’s been 2 weeks now since I have gotten drunk so should I be 100 percent back to normal now or am I still facing brain damage like the “experts” say? Personally I don’t think I am but who knows.
