I suffered from severe social anxiety for pretty much as long as I can remember. In my teens I was put on sertraline which did nothing except give me bad side effects, and after that I swore off psychiatric medication. Finally last year I gave in and decided to see a psychiatrist again after spending a year unemployed and unable to get through a job interview. I was on paroxetine for a month and it was worse than sertraline, hellish and horrible and did absolutely nothing for anxiety or depression. Then I was put on mirtazapine and lorazepam. The mirtazapine worked for putting me to sleep (although it gave me vivid nightmares and made me so sleepy it was hard to wake up in the morning), the lorazepam was too weak and didn't last long enough, if I took it in the morning I would experience rebound anxiety by the evening unless I was willing to take more than the prescribed dose, so I was finally put on clonazepam...which has been a miracle drug for me. My doctor prescribed 5mg a day although I only took as many as needed. 0.5 did nothing, 1 helped a little, 2mg worked wonders although my tolerance of course caught up to me. Since then I've gotten a job and some semblance of a social life and have taken part in things I never thought I would have the courage to do. (Of course I've also done some stupid things because of the reduced inhibitions, but my psychologist says that's just my own poor judgment coming out that I need to work on and the meds are not the cause.)
I regularly see a psychologist to conduct cognitive behavioral therapy, however he was the one who suggested I go on benzos in the meantime since CBT can be a slow process and my life was wasting away.
The tolerance and dependence issue has always caused me some anxiety (which is what the clon is supposed to be treating), but with a slow taper withdrawals can be kept to a minimum. After being on it for six months I tapered down until I was off it for about a week, I had minimal withdrawal symptoms but once I was off it I was back to being the same old socially anxious mess, the anti-depressants were doing nothing and the CBT hadn't worked yet, so I went back on them. Clonazepam fortunately has a very long half-life. I've found I can go 3 whole days without a dose and not experience withdrawals (Note this is only my own personal experience and I would not suggest foolishly experimenting to see how long you can go without a dose since everyone is different), only on the 3rd night without taking clon did I experience a very unpleasant night with some crazy withdrawal things going on that terrified me. But overall it has a much longer half-life than compared to say, alprazolam, it may take longer to get off of clonazepam but the withdrawals will be milder. If you google benzo withdrawal symptoms you can find a frightening laundry list of things that will make it sound like quitting benzos will plunge you into the depths of hell. But everyone has different body chemistry and reacts to drugs differently, only a certain percentage of the population will experience one withdrawal symptom or another. Some people won't experience any significant withdrawal symptoms with a slow and steady taper.
So clonazepam, like all benzos, is a double-edged sword. I would suggest finding a good talk therapist and trying cognitive behavior therapy to try to cure the anxiety. In the meantime you have to treat it the best way you can. My goal right now is to get to the point where I can switch to using benzos on a PRN basis rather than a daily basis. I'm planning on soon doing another taper down to zero- being on it non-stop for years would definitely scare me.
One way benzos like clonazepam are supposed to help anxiety is by making you realize you can do things you thought you couldn't do without the sky falling down on you. As my psychologist put it, giving someone with a fear of flying a Xanax and putting them on a plane isn't curing someone of their fear of flying. But after they've flown a few flights with the Xanax they realize they're not going to die by hopping a flight and will be willing to fly without needing the Xanax. When I first started my job I felt I needed to take clonazepam every day in order to function at work or I would be afraid to even walk in the door. Eventually I realized I don't need it as I got used to performing my tasks and interacting with my co-workers, my fears were unwarranted. So there is a method behind therapeutic use of benzos when it comes to curing anxiety beyond what benzo detractors would claim is just "masking the symptoms".
