I don't know the details of your addiction but the best way to cease any substance one is addicted to is to wane off it, cold turkey can be pretty horrible.
Here's the thing, one of the most powerful types of benzos is rohypnol (flunitrazepam), so I'll give a waning regiment starting with that...
Rohypnol/flunitrazepam --- slowly lower the dosage then move to
Klonopin/clonazepam --- repeat slow dosage lowering then move to
Xanax/alprazolam --- repeat slow dosage lowering and eventually cease OR move to
Alcohol --- not a benzodiazepine but affects GABA neurotransmitter activity in the same way, which is why extreme alcoholism leads to similar withdrawal symptoms
===> If you move to alcohol you can start with it at about 3 glasses of wine spread out over the whole day (with each meal) then eventually lower it down to 1 glass a day which is a healthy consumption amount that helps prevent heart disease (red wine)...or you can cease entirely
****Medical attention is something you should seriously consider seeking as with GABA-related addictions seizures may persist indefinitely, I personally have a former alcoholic in the family who has been clean for several years yet still experiences severe seizures...
As for substances that might help your withdrawals, I know that Nootropil/Piracetam is a natural derivative of GABA and seeing as the main problem with GABA-stimulating substance withdrawal is a lack of synaptic GABA, it might help... Nootropil/Piracetam is actually approved in many places for the treatment of Alcoholism and seeing as the neurological effects of alcohol withdrawal and benzodiazepine withdrawal are extremely similar, I am sure that it should help.
Ibogaine has only been researched for and proven to work for the termination of opiate withdrawals, there is some evidence that it also helps with alcoholism and stimulant addiction but considering it is illegal (Schedule I) in the United States and they recently (2005) started prosecuting people for importing it using internet connections, it would be a very dangerous substance to seek. If you wish to risk legal action, the best route to go would be to attempt an extraction from the legal, native plant, Chinese Star Jasmine/Confederate Jasmine... You might also wish to book a "vacation" to Mexico or Canada as there are many ibogaine addiction treatment facilities in those countries and the period of time required for in-patient ibogaine treatment is extremely short in comparison to other detox programs.
Speaking of illegal substances, there is some research that shows that LSD helps with alcohol withdrawals (again, extremely similar to benzodiazepines) and someone I know actually watched a friend of theirs go through alcohol withdrawals whilst under its influence, the friend did not experience any seizures, only minor tremors, and experienced very little personal discomfort. Again, this is a risky way to go as you are living in the United States.
Whilst I'm on a roll I'll give you one last suggestion that would probably not be a good idea, due to the impairment involved. Recent research from MAPS (the multidisciplinary association for psychedelic studies) and other organizations shows that ketamine may help deal with the pains of all kinds of withdrawal, including alcohol/benzodiazepines, and it definitely helps with withdrawal related seizures...ketamine is illegal....HOWEVER, a very, very closely related substance, dextromethorphan is readily available over-the-counter, it is the active ingredient in several cough medicines (if you are looking for it be sure to choose a medicine that contains ONLY dextromethorphan and nothing else, one suggestion would be Robitussin gelcaps)... the real catch with this one is that in doses that are high enough to stave off the withdrawal, there's plenty of impairment, dextromethorphan/DXM is a dissociative anesthetic hallucinogen... recreational doses of robitussin gelcaps range from 10 to 80 caps, with 10 producing mild dissociation, euphoria and some dizziness.
ALL of these suggestions are risky, as like I stated earlier, there is a risk that you will be prone to seizures indefinitely following cessation of benzodiazepines after developing an addiction...
Good luck.
