For the most part I have a lot of really clear memories, even from my distant past.

My short-term memory isn't necessarily all that great though... but significant events I always remember.

I do have a quirk when drinking though: my first "sign" of being a bit overly drunk is short black-outs. Unfortunately I will be unaware of it until the next day. But I'll have black-outs without having hangovers or any signs of sickness, and I'll have been in good control of my body and conversations. I just get black-outs early on.
