A cough syrup that makes you drowsy.

Damn it, only now do I realize that she is addicted to wine (remember the proseco?)
More specifically, the answer is red wine.
BLOODY RED WINE the addicted drinks four liter this ev…and you Samuel? Will ya join in @gatsie, I bring two bottles U2?
@samuel_the_leader you go, gatsies riddls are too tough [aka 9 days etc…]
Here’s one with an unrealistic and far fetched -ish answer.
A man somehow comes into contact with some kind of lethal disease and washes his hands immediately. However, several hours later he dies of the exact disease he came into contact with. How? Also the disease is only transmitted through direct contact.
Earphones: Can we trade? Yours for mine and mine for yours. Guess what modifications there are to it that make sure it won’t slip out of your ear?
Is this a riddle or a question. Are they once with the band thing that goes behind your earls like a bluetooth?
Elaborate on that. (Show pic if necessary)
My ears are too small for these things. I prefer headphones 
Is it ebola?
No, it’s just some disease, it remains nameless for the sake of the riddle and because it’s most likely not real.
Uh ok then.
Then he simply died because he was already dying due to the mysterious scifi lethal disease he was infected with.
Nope
I think Gatsie meant that (via contact) the disease infects immediately, so washing immediately (can’t possibly be more immediate than the disease) is futile. The best bet is to never allow contact at all.
Oh, no, not like that.
Then like what?
The man washes it off, if you get it on you you can wash all of it off with no further effects (unless it’s on you for too long (over 30mins lets say))
How convenient. I just realised I lost them. 
Did you lose them in your house?
