I have been on Norco for the last 5 or so years. Last Monday I decided to get off of it. I actually checked into a rehab but left after several days of waiting for the withdrawal to begin. The only real symptom that I have is insomnia. I was taking 5 to 8 Norcos for those years. I have slept maybe 10 hours over the last 8 days. I am exhausted. How long do I have to put up with this misery? I feel like a zombie, I literally pray to GOD for sleep. I don't want to overdose on over the counter sleep aids. I don't want any prescriptions but I am getting desperate. Anyone here have any recommendations? or does anyone know about how long this insomnia will last. I really am starting to hallucinate and having a hard time focusing my eyesight. I am a nervous wreck and I am so tired that I am petrified. Should I go to the emergency room, psychiatrist...? please help with recommendations.
