I can't tell you that. Benzos are a medicine, not to be played with. If you think methadone is addictive, wait to be addicted to benzos...
Really man, you should not take benzos every day, not worth it at all...
This guy above me is right.
I know this is a long post, but it contains some knowledge that few people know about which can end up fixing you and countless others up. That knowledge of what anyone can do, legally, and improve their lives is below the double scored line in this post. READ IT. It will be worth your time.
Imagine being slowly burned inside, unable to sleep, and going crazy all at the same time for an entire month. THAT is the type of agony involved with getting off (withdrawal) from your Xanax and Valium. The withdrawal can kill, too, and causes seizures if not controlled.
Imagine an emergency situation where you can't get Xanax. You'd be BEYOND screwed. When I cold turkeyed the Xanax I was on, I wanted to die for an hour or two EVERY DAY. It's that bad, man. Avoid it. Don't screw yourself. Learn from MY mistakes, so you don't have to learn first-hand!

Now here is the education below on what you can do instead, and end up feeling great. These work, too, especially the third one. This isn't some mumbo jumbo holistic BS I am about to write, either.
I'll give you three alternatives you might be unaware of to help you out in place of using your benzos.
Kava kava is a natural supplement used for thosands of years on the islands of Hawaii and thereabouts. It makes you feel relaxed like Xanax but without the addiction issues.
Valerian is very similar in respects to your benzos too. Acts in a similar way, helps to calm and to sleep, and doesn't carry many side effects except relaxation and drowsiness, in my experience. In fact, I beleve they modfied the compound in valerian and MADE Valium from it. Notice the similarities between the names valerian and Valium? One came from the other.
And finally, my favorite, Kratom! Kratom mimics opiates closer to anything I am aware of that can be sold legally, and it most certainly works, too! One moderate dose of an extract or 6g powdered leaf has the relatve potency as about two or three 7.5 hydrocodone. Yet, it doesn't make most people sleepy. It also acts as a stimulant, and gives a lot of energy while giving a portion of euphoria like opiates. I liken it to a cross between hydrocodone and adderall. The only side effect is nausea if you try to take too much. Unfortunately, in your case, the methadone dose you are on would almost certainly stamp out the effects of this wonderful gem of a plant called Kratom. I would suggest that once you get off the methadone and your tolerance is back to lower levels to give Kratom a shot if you find yourself craving opiates. The Kratom entirely destroys all desire for me to return to opiates while I am using it.
Those are just a few things I know. I know A LOT about medicines and supplements such as the ones above. If you are ever in trouble or have a question about things like these, I would be more than happy to help you.
One final thought: Kratom is what I personally deem a "functional opiate", meaning it doesn't screw up your day and make you useless anywhere near as much as pharmaceutcals like your methadone. The withdrawal from kratom is cake compared to classic opiates, too. Kratom works on nearly all the same receptors as morphine, and contains two mai. ingredients that bind to those opiate receptors, with one of those main ingredients in Kratom found to be several times more potent analgesically than morphine. You will concentrate better due to the added bonus of the stimulant effects, feel less pain, and I estimate the addictive potential of kratom to be about a fourth as bad as lortab.
This is where I get mad again. Nobody prescribes this amazing little plant, and the applications I can think of for Kratom range from a powerful antidepressant, potent painkiller, keeps cravings of hard drugs away, useful in withdrawals from Xanax to opiates and all the way to amphetamines, can't OD on it easily, works well for ADD/ADHD... The list goes on and on.
It blows my mind that people and pharmaceutcals are scarcely aware of it's existence. Heck, I might go into pharmaceutcals and make millions off it.
Any questions, feel free to ask, friend.
