You've gotten some great answers and I think what you describe could certainly have been because of your attempt at tapering.
My experience with tapering and then quitting were like posts #16 & 17. Lots of hallucinations.
Go to a regular GP, tell them your story. Referrals are up to them.
You can get a week's worth of inexpensive meds to help you get off the drink safely and completely without all the symptoms if they are in fact only withdrawal. Why don't you do that? All this fear isn't good for you regardless of the cause. Just go to the doctor. They've seen it all before.
