How do you treat the cause of physical anxiety without drugs? Not everyone experiences anxiety as rumination. I don't excessively worry about things, I just feel physically uncomfortable all day. There's no talk therapy that's going to verbalize that away.
I'm not a psychologist or a psychiatrist, but I'll still give this question a try. First of all, what is physical anxiety? Is it an entirely separate problem from "mental anxiety"? If so, where does it come from? Why would the body be creating symptoms of anxiety without any influence from the brain/mind? I think that the mind/body link says that there must be some connection, even if you experience anxiety primarily as physical symptoms and not thoughts. I think it is much more common for at least
some level of thought to accompany physical anxiety, but I'm not saying I don't believe you. Did you, at any point, have "mental" symptoms of anxiety? I wonder if there could be some kind of subconscious notion influencing the anxiety. That's a difficult area to comment on for a non-psychologist.
I still think that CBT can help people with "physical anxiety", and here's why: Even if you're not having anxious thoughts now, if you had positive and relaxing/reassuring thoughts (do you have these already?) then I'd imagine that those thoughts would result in a decrease in your physical symptoms, especially if you actually
believed in those thoughts. Maybe not, but it does make sense if thought can influence how you feel (and that has been proven).
Drugs are very effective at stopping the physical symptoms of anxiety. But tolerance develops to everything eventually, downregulation happens and there are other side effects. My psychiatrist always asks me if the "side effects" of the anxiety are worse than the side effects from the drug, and I think he has an excellent point. Some people may be better off on a medication, but if they're going that route, perhaps they should be on some kind of rotation of substances in order to prevent tolerance and dependence. An antidepressant might also be more worthwhile than a drug that offers immediate relief. There is a reason why benzodiazepines are not recommended to be prescribed for the long-term. And pregabalin isn't any better, in my opinion.
I don't know, these are hard questions to answer. I personally would not take any drug that can also be used recreationally (gabaergics) daily, but that's because in my opinion it's not that far off from taking ethanol every day for anxiety.
