Withdrawl affects? Had been on ambien for 12 years nightly?

Added 16 Jan 2010:

Thank you for your response. I have told the doc about this. I've changed states so he was unaware of all the things ambien was helping me with although he could see the difference in me while on it and off of it on two different occations. He has done what he can to try and get medicade to pay for the non generic as has the pharmacy. Unfortunately Im in a remote area and the Teva is all they can get besides the real thing. I am on xanax as well along with the ambien, again the combination of these mads were a life saver for me. Its a real struggle as my symptoms (illness) is also reported as the same as withdrawls. This being the reason medicade along with the FDA reports about long term use is refusing to pay. They did pay for the Apotex brand, which did work, but of course they no longer make it.
Id also like to mention that for 21 years my daughter and I have been disabled but not always on the same treatments. That when using a generic brand of medication U.S.A Tiva brands never worked and caused more harm then good. I am not the only one that has had the same complaint and even the pharmacies do not like the brand. The pharmacist recommended I obtain the better brand via the internet and that I could probably get it at a much cheaper cost but dont know who to trust (suppliers).
Also, I can imagine that I am one of the longest users of this medication and not for what it was intended for. I think my case would be of benefit for others that suffer with my disorders, what my side effects were while on it and now, actually 4 months off of it.
One more thing. I was told to go cold turkey off of the ambien can be dangerous and life threatening as is my illness. Am i past the life threatening part of not being on the ambien (with drawls)?
Thank you again for any help you can offer.
Sincerely
