K, do you have long hair?
If so, try putting it in a plait before bed. I used to do this when I had long hair, no matter how drunk.
Facial wipes! A key component of the handbag.
Ditto those Oral B throwaway toothbrushes.
If I were out to go get laid, I had a kit: condoms, a couple of facial wipes in a small plastic bag, Optrex eye drops, throwaway toothcleaner and TINTED LIP BALM!
A must b/c then it looks like you're just putting on lip balm.
Laura Mercier tinted moisturiser.
End of.
Youth and good looks help, too, although I no longer possess those.
