I am also on the withdrawal from clonazepam. I used to take 1mg on demand, sometimes more than that at once.

After years of using benzodiazepines on and off, my system has gotten used to them. I've tried alprazolam (Xanax), bromazepam (Lexotan) and the last one was clonazepam. Considering the high potency of clonazepam compared to other benzos, quitting it cold turkey is not advised. Well, actually quitting any benzo cold turkey is a bad idea. Withdrawal itself already mimics plenty of physical and psychological symptoms like you said, and quitting any benzo cold turkey is very dangerous, it could cause seizures, even death.

The best way is to taper off, using Diazepam (another benzo) due to its long half-life. It's a long-acting drug compared to other benzodiazepines.

I know how it feels, my body was having all sorts of weird symptoms from withdrawing from clonazepam. Three days into not taking it I had intense restlessness and agitation from within, as if I wanna scream out all the pain. I got irritable, had muscle jerks whenever I was about to sleep, and a sense of impending doom, as if death is around the corner. And the sleep apneas...Scary.

The withdrawals also manifest itself as symptoms very similar to fibromyalgia, and I suspect my acid reflux is the result of lacking of benzodiazepine (the required amount) in my body.

Well have you ever checked out the Ashton Manual? It is developed by a professor to help people getting off benzodiazepines and available online. Since I don't take benzo regularly, I now replace clonazepam with diazepam once a week. And gradually tapering diazepam off.

It's going to be a very slow process for you, since you've been taking Klonopin for more than 20 years.. still amazed that you've survived it cold turkey quitting. Very amazing.
