Anyone to provide stories of how they successully got off benzies like Ativan? and what next?

My new psych told me on my first vist that I had to get off Ativan urgently.  I have been taking it for about 15 years, first to sleep, then to wore down to allowing me to take the edge off.  He cut my Ativan in half from 6mg to 3mg within a day and said that he will not relace it with anything else, although I know that low does of Seroquel prn helps too during the day, have not had experience with an increased dose at night.  Anyone had experience wening off of benzies and how did you deal with the aftermath with no replacements and also the withdrawal symptions?  Please help me!  I am deperate and scared out of my boots.  With all of the other change, that has been the only consistancy that I could count on to help.  How do you sleep?  How do you calm yourself when stressed or upset in anyway.  Yoga, reiki, massage, meditation did not work for me.  Makes me feel like a waste of everyon's efforts sometimes, life I am a waste of life consuming space better used by someone else.  Please benie withdrawal and what next would be GREATLY appreciated - personal experience, observation, dr's input, anything really.

Thanks in advance!
