I hope you don't mind me wandering into the conversation, I'm not a healthcare provider, but I am, or at least was, a patient who went through the Ashton Protocol to withdraw from Xanax (I enjoy reading some of the discussions on here, particularly the research based ones). Quick background, I was on Xanax on and off for a little over 8 years for treatment of panic and anxiety disorder, the last four of those I was on a daily average dose of between 8 and 10 milligrams. Initially I made the mistake of trying to jump off cold turkey, I'd been warned not to, but I didn't listen, and I thought I could handle it - one grand mal seizure, and a trip to the ER later, I realised I was wrong. . When I eventually did the Ashton Protocol, under a Psychiatrist's supervision, it was a lot better, but I still had to go through a withdrawal. I don't know if its the same with other patients, or if there's been any research on it, but just personally I found that once the physical withdrawal was over, it still took me several months to feel completely normal. I felt like I was having difficulty processing sensations, I had trouble differentiating between what was a normal state of stress, and what was the start of a panic attack, I couldn't always tell the difference between normal daily aches and pains, and stuff I should be worried about. I went through something similar when I did a methadone withdrawal program after being addicted to heroin, it's kind of like your brain/body needs an adjustment period of rediscovering what baseline 'normal' is actually like (I'm sure you know this stuff already). It did eventually settle down, and I have absolutely no residual or ongoing issues related to either my use of Xanax, or my withdrawal from it. I think though, had I found one of these types of support groups at the time, it would have been very easy for me to believe the 'blame everything on the benzos' rhetoric, because it probably would have made that post withdrawal adjustment period seem a lot less confusing. I can also see how it would then be possible for a person to become mentally trapped in that state if they're constantly surrounded by, and interacting with people that are reiterating that every little twinge is somehow related back to benzodiazepines use and/or withdrawal.
Just a layperson's 2 cents worth from a personal point of view. Not sure if it's helpful to your interests, so feel free to disregard, or take from it what you will. 😎
edited to add - sorry, just one more thing I thought of. I did find after trying to come off Xanax cold turkey that I was very fearful of withdrawal for a while after that, simply because that experience had been so frightening. I needed a lot of reassurance from my primary caregivers when I was doing a tapered withdrawal, because even the mildest of possible withdrawal symptoms had the potential to send me into a total panic of 'Eek, this is going to be bad, really bad, I'm going to have another seizure, I'll end up in hospital again'. It did make me very hyper vigilant, and hyper aware of what I was experiencing, even during a slow withdrawal, that I knew was safe. I wouldn't be surprised if other patients, or former patients felt the same way, or had experienced the same types of feelings. I also wouldn't be surprised if that fear/hyper vigilance/hyper awareness manifested itself post withdrawal as well. I'd personally love to read some research on this myself.
