Take some benadryl. You shouldn't go cold turkey, you should gradually lower the dose.

Your body will ache like you have the flu. You won't be able to sleep, or you'll have a hell of a time staying or falling asleep. You may get the cold sweats and twitch a lot. That will last for less than a week. You could try taking Valium if you have it available.
