I don't feel like writing a long response here, but out of all the drugs I've done (which is basically everything), alprazolam is the most addictive.
My Xanax/Klonopin addiction was the worst thing I've ever been through in my life. I can't explain it all here right now. That was an 11-year battle for me. I could always quit everything else, but not benzos. Now I've been off them since November '13, and I have all kinds of messed up long-term side effects appearing even now.
But I guess everybody is different, right?
Would you believe me if I told you that, due to my tendency to deliberately skip a dose (or completely forget about it), I have amassed so many extra Xanax pills that I don't know what to do with 'em?
I was first Rx'd the stuff back in 2006 for Panic Disorder, Anxiety Disorder, and off label to help with side effects from an SSRI (Zoloft) which I was simultaneously placed on. 0.25mg TID; then I went up to 0.5mg TID and have not dared to go any higher. In fact, now I've managed to go down to 0.5mg OD (morning) + 0.25mg BID (afternoon + evening).
On the other hand, I'm terrible when it comes to opioids. I have a tendency to escalate my dose a lot admittedly. And for that reason, I might be dead if it wasn't (at least in part) due to help from fellow Bluelighters such as yourself
So yeah - I think that genetic makeup plays a bigger role than we might think. Why else would we apparently be polar opposites, so to speak?
I don't mean that in a derogatory manner. On the contrary, I can definitely empathize with your situation as it relates to benzos because I too have been forced on a number of occasions to go cold turkey, and let's just say that it was beyond awful to deal with, and that I was useless for a couple of weeks (couldn't function worth shit).
Edit:
Perhaps this shall help you (or not): The last time I had to go cold turkey off of Xanax (Alprazolam), I happened to have a bottle of Lyrica (Pregabalin) as well as Inderal (Propranolol) at my disposal (oh, and some 'Baby Aspirin'). And I must say that, by themselves, high doses of either Lyrica or Inderal helped a lot to dull the withdrawal symptoms. When taken together however, I was only left with some mild insomnia, but amazingly no anxiety and/or panic attacks.
P.S: I was taking the 'Baby Aspirin' in order to thin my blood (obviously, LOL) because I'm paranoid about getting a heart attack ever since I experienced my very first panic attack (which I thought was a heart attack - either way, it was extremely unpleasant and I'll likely never forget the day that it happened as a consequence). Whether or not it dulled withdrawal symptoms, I don't know, sorry.
P.P.S: Even Valerian, Chamomile, Kava, Melatonin, Magnesium and such may help dull the withdrawal symptoms (in case you haven't tried any of 'em). But are they contraindicated for some reason when withdrawing from Xanax? That I don't know.
Either way, for what it's worth, good luck man
