I just went thru Klonopin withdrawal -- been off for about 62 days if I remember correctly. I was on it for almost a year. Up to 2mg/day in .5mg increments. After a while, I naturally weaned myself down to 1.5, then 1, then .5mg/day. Finally I made the decision that I wanted to come off of it because a) I never planned on being on it that long b) at some point I want to get pregnant. So I took myself down to .25mg/day, then dosed every other day, then I came off. Even at that gradual taper schedule, I was going thru something. Nothing I couldn't handle, but it was still rough.
The sleeping problems and rebound anxiety were the worst part. I took Melatonin for sleep....it was somewhat effective, though, honestly, not as much as I would have liked. I took Niacin for anxiety...its just Vitamin B3. I took I think 500mg at a time, but you might want to start with a drastically lower dose if you try it because it causes a "flush" which makes you itchy and warm. I don't mind the feeling, but it could be annoying. The Niacin did help with my anxiety a lot. I also drank a lot of coconut water (Vita Coco) during my "detox". I don't really know if it helped; it was probably mental. But I felt like it did.
The worst of the Klonopin withdrawal was about the first four days after I took my last dose. I felt like I was gonna freak out. I was also in a much different situation because I had given myself permission to take it in case I really and truly thought I couldn't handle it. I carried the Klonopin with me in my purse for the first like month. I needed that safety net. Knowing I had it if things got really bad was helpful to me. After about a month, I started leaving it in my car. I still wouldn't want to not have it in the car, just in case. (In fact just now as I thought about leaving it at home instead of in my car, I felt anxious, LOL.)
I just recently started taking a new herbal supplement that contains Valerian Root, Scullcap, Chamomile, and some other things. Its really helping me a lot, I'm actually surprised at how much. I also take SAM-E (for depression), Omega 3's, multi-vitamin, probiotics, and an immune system booster a few times a week. I also got liquid Valerian Root for help with my lingering sleep issues -- but I think my sleep is actually back to where it was before I was on Klonopin, which was somewhat problematic.
Now, all I can promise is that it definitely does get better. And aside from isolated incidents of very intense anxiety, I actually feel LESS anxious off the Klonopin than I did about half of the time. I think the roller coaster of taking benzodiazepines made me feel variably less anxious, then more, if that makes sense.
Good luck, and sorry for the book. ;)
