I went through klonopin withdrawal on my own at home. The most agonizing three days of my life, and it took nearly 6 weeks to start feeling normal again. My doctor had tapered me down, but it was a 3 day taper which was ridiculously short. I was also drinking on top of it.
Whatever you do, it should be done VERY SLOWLY, especially if you have been on a relatively high dose for a long time. Do some online research to be your own advocate, and work closely with a doctor.
