There are no cures but if you drink 2 large glasses of water before you sleep that will at least stave off the main issue in the morning which is dehydration.
Food when you wake up will help your stomach.
When on my golfing holidays with the boys once we have had a full fry up we feel brand new. A round of golf, which is 3.5 hours walking and exercising in the fresh air helps tremendously.
In fact you are just about "cured" by 5 pm which is handy as that is when the first pint of that days bender is sunk
