Please think really hard about the inpatient rehab. I have done it, and it was a horrible experience. I always advise others not to do it. I know you are hurting bad right now. I can almost feel the pain in your post. I was just like you in 2006 when klonopin decided that it no longer wanted to work in my brain anymore. When you get really sick from these drugs, the 1st thing most pdocs will do is try to push you into detox. They simply want to wash their hands of you at this point. Mine did the same thing to me. He literally abandoned me at a time in my life when I needed him the most. I was so desperately ill during this time that I consented, and it was the biggest mistake of my life.
If you go to detox, here is what is going to happen. You are still taking one mg of K. They will probably give you 1 mg of K on day one plus start you on a cocktail of other meds that will in no way mitigate the effects of the bzd w/d. Day 2 and3, maybe .5 mgs of K. Day 4 and 5, .25 mg of K and then day 6, they take you off. The detox protocol these places use is essentially a CT IMO. Why go there, lose all control, and be confined when you could do the same thing at home if you wanted to? They do give you anti-seizure meds but you are already on gabapentin. If you could taper the K down some more and get her to write you a script for valium, start taking it, and give it enough time to build up in your sys, it could help like it did me (worth a shot IMO). It did work for me. As more days went by with no klonopin, the valium built up started to work more and more until I did finally stabilize. K is such a potent benzo. At first, I thought the Valium was not going to work bc I did not feel much relief right away, but as the klonopin left and the valium built up, I started feeling more and more relief. I am just relaying my personal experience on to you for you to consider.
