Warmed up double blackberry brandy and honey, maybe at least two, an hour before bed. Even if it doesn't work for you it's delicious anyways. And maybe three aspirins right at bedtime. Did you get sore throat spray. That's usually a numbing and maybe peroxide healing spray concoction. I add a tablespoon of peroxide. Small amounts mixed in other stuff is normally not harmful.
But as your usual you may check all of that and probably should. Probably don't need to fact check the blackberry brandy as that has been around for centuries.
