Apart from being possibly dangerous and fatal, every unsuccessful cold turkey effort also reinforces a negative component of your behaviour, ie giving up on an effort.

When you seek professional help later, this behavioural component will work againsts you. It is better to taper off.....try to cut down even a little bit on a day to day basis. And seek medical help soon when you have the time.

I am not trying to discourage you. But the worst thing you could do right now is making giving up a habit.
