Honestly, there’s no magic cure, just damage control. What’s helped me most is drinking a lot of water (or ORS/electrolytes), eating something light like eggs or toast, and getting proper rest; coffee can help the headache, but don’t overdo it if your stomach’s off. A pain reliever like ibuprofen works, but only after you’ve rehydrated a bit, never on an empty stomach. Next time, the real “cure” is pacing your drinks and having water in between.
