LOL, I love it! Try to keep to yourself when you first get "inside" but you may end up having to join a jail gang to make it all the way through your 5 days without some DUI offender doing weekends makes you his bitch. You may go in Monday with your dignity, Wednesday you are wearing a dress and crushing up crayons for makeup and by Friday you are afraid you wont be able to readjust to life on the street after your bid! LOL
Seriously though, 5 days isnt shit. Just stay up partying for 3 days before you go in and enjoy the rest. Hell pop a few xanax right before you go in and when you wakeup it will be halfway over.
I had to do some time and before I went into court for my sentence I popped some klonopin and the next thing I knew, I was waking up two days later and was already done with all the processing and other bullshit.
Drugs, they'll get you sent to jail, but they'll help you through it too
