Idk, I used to take 10 - 25 Xanax (alprazolam) 2mg Bars a day. It eventually just became my regular state of mind. The only way I would get fucked up was when I would mix it with opiates back then. And I used opiates everyday. So I would pop about 5-10 2mg bars in the morning Shoot a nice shot of tar (around .1 or .2) or Would snort 2 80mg Oxycontins and take the bars. And smoke a lot of really dank weed, hash, kief. The way I managed to always stay fucked up and but still have a tolerance was to mix it up a bit. I would take different types of bars like the yellow's or the Green's or the cut backs or the smooth backs. I would switch around as they all have different time releases. Or take foot balls (the 1mg's) or other benzos like Valium (but I would have to take so many of them to even feel anything I barley ever messed with them) or K-pins (clonazepam) and so forth, I never really cared for ativan (lorazepam) because it always made me really depressed after long term use. I would sometimes take them and let them dissolve in my mouth with a soda and then swallow it for it to instant release or just take a bunch of them or break them in half, chew them up. With opiates I eventually just started slamming them, and so I stayed high. But this is about benzos I'm getting off track.
Well anyways hope I helped.
I am in no way telling to take that many or to combine opiates and benzos its a very dangerous combination and you have to have a high tolerance to both of them to do what I was doing.
I am on the Methadone Maintenance program now, and still take Alprazolam (Xanax) regularly as I am waiting to get prescribed. But not near as many as I use to take. I will ussually take 2mg's in the morning and 2mg's at night. But if I ever get anxiety or a panic attack I would take another 2mg's. I try not to abuse them anymore, because they are a hell of a drug to come off of, especially when you are on the amount that I was with the amount of Opiates I was doing.
Good luck, and BE SAFE.
