That was fun, wasn't it?
But I guess you really could use something to drink after getting so worked up.
Have a glass (300mL) of water. Yes, just normal, plain water. It's important to keep yourself hydrated.
Then make some coffee, one big cup, same size of your water glass should be enough for now. (If you are sensitive to caffeine, feel free to substitue all coffee with tea)
While you're waiting for the coffee to brew, you should use the time to use your toilet. Trust me, you don't want an already filled bladder for the next steps...
