Good or bad bet?

[Badger]

So I just made a bet with my roommate. $250-$25.
The bet is he can only eat celery for 1 week.
He can drink basic juices (orange, cranberry, apple, no shakes or smmothies).
He can take a multi-vitamin and calcium pill each morning.
He can drink booze with approved juices. He can drink beer. He can smoke. He can also drink water.
Good or bad bet?
What might make this a bad bet for me is I gave him a 24 hour opt out. It starts Sunday at midnight, so he can opt out Monday night.

Edit: Yes I've been drinking a lot, and yes I type well even when I drink.
