"Hurry up and wait."
There will be a lot of waiting, and when you arent waiting, you'll be running around like a chicken with its head cut off.
There will be a piss test with an hour of getting there, so try not to pee when you wake up.
There will be a breathalizer test before any other tests are given.
You will get your blood drawn, but just grin and bear it.
You will be in your boxers with other guys, but again, grin and bear it.
You will get your junk felt, and you'll bend and spread. Again, grin and bear it.
They'll feed you, so you dont need to worry about that.
They have arcade games you can play while waiting, so bring a couple bucks.
Carefully think about everything you put on paper.
Do exactly what they tell you. No more, no less.
DO NOT BRING WEAPONS TO MEPS. I had a pocket knife the first time I went, and was lucky enough to have my recruiter there to put it in his car. There will be security screening of all bags, coats, and people at the door.
Keep in mind, Im a guy, so these partain to guys. I dont know what a womans physical would entail.
Hope that helps.
