*hugs* It'll be okay. You'll get through it, but you should know that there will be withdrawl symptons. Agitation, a low grade fever, depression, fatigue, headaches, and nausea are all to be expected while you go through this difficult period.

If the bad dreams, night sweats and insomnia last for more than 6 months, you should consult a doctor. But don't worry about the black outs. It helps to block out the pain. (Oh, the pain!!)
