“are you alright? you hit your head pretty hard…”
Lights were spinning and the pounding inside of her head (which at one point was a literal pound as she hit the ground) was on the verge of intolerable.
She heard someone’s voice-- were they asking if she was fine?-- but otherwise was deaf to whatever was going on around herself.
“Hah....Naga alm--ugh.” She held her head, a bolt of pain striking her head. “Goodness, that was the worst thing... I could have done.”
You surmise she...probably was drinking. A little? A lot. Definitely a lot. Was it the first time she ever got drunk? Probably.
“Oh...I’ll be fine. I’ve been through worse. Thank you...and excuse me.” She got up painfully, heading toward the bathrooms of Venuz Patrol. It takes her a little bit, but she manages to reach a stall.
There’s no need to describe what happens in there knowing her condition.
