Thought you might be interested in this, jealibeanz. Probably you think it doesn't apply to you, but it could explain why the xanax XR doesn't help right now.
Also why the XR might be better for you, in the long run, if you stick with it and your brain adapt to a different rhythm of release, possibly by making more GABA itself.
It's admirable that you're sticking with it this long, given how difficult it's been. But you may experience a change in your adjustment to it soon; I hope so.
That might help in general.:
This is from a pdoc's blog on blogspot. I'll look for the url.
"This is in response to JW's question below about the "rules" docs use about prescribing Xanax/alprazolam. Not all docs feel this way, but here's how I think about it. Of course, I am not suggesting that, if you are taking this anti-anxiety drug, you should stop it. I'M NOT. Talk to your doctor if you have concerns.
The half-life for Xanax is short... on the order of 6-20 hours. Halcion is the only similar sedative that has a shorter half-life (and that one has even more problems). Thus, it doesn't stick around long. It is also quite lipophilic, meaning that it quickly gets into the brain. So, it has a quick on, quick off way of working. Sounds great, right?
The quicker a drug works, especially one which makes you feel good in some way, the more addicting it is, as the cause (taking it) and effect (feeling it) are close in time, making it very reinforcing. This is fine if you just take it on those rare anxious moments where you need something to get through it. However, since it works so quickly, many folks start taking it more and more often, until it gets to the point that they are taking it daily. Then they start taking it as soon as they feel it wear off. Before you know it, you are taking it 3-4 times per day. Now, that's not the big problem.
The big problem is all because of your brain's laziness. See, your brain makes it's own natural Xanax-like substance, called GABA. GABA works by inhibiting the brain's natural tendency to speed up. It's like a brake pedal, where the accelerator is stuck in the pedal-to-the-metal mode. GABA keeps your brain from over-working. Xanax (and other sedatives, and alcohol) works by acting like GABA in the brain (sort of). If you start taking it daily, your brain starts thinking "I guess I don't need to make so much GABA because this Xanax stuff is here, so I'll only make 20% of what I usually make." It takes a week or more for your brain to stop making the GABA (which is why just a few days on Xanax won't lead to much trouble), and a week or more for it to start making it again when you stop taking the Xanax.
Here's where the trouble begins. If Xanax wears off in just a few hours, but it takes a week for your brain's natural Xanax to kick back in, what happens in the interim? Withdrawal. What does that feel like? It feels like a panic attack, but worse. High blood pressure, rapid heart beat, tremors, confusion, delirium, hallucinations, seizures. What do folks do when they feel a panic attack coming on? Take another Xanax."
