If stopping that cold turkey is ANYTHING like xanax cold turkey, it could have killed you. In my case, in which I am in process of filing complaint against doctor, I had to switch doctors, stayed with Premier Medical practice, because of insurance issue after I went on disability at 62. I called for a week and she didn't refill it. I went to hospital twice in 24 hours, didn't sleep for over 48 hours straight, didn't eat for 5 days, it was horrible. The nurse manager finally called them in for me after my sister, who is nurse practitioner, figured out it was xanax withdrawal and really messes with your perception of things. I had to throw out so much food because it all tasted like dirty musty socks smell, milk smelled sour, EVERYTHING that was scented was 1000× magnified. I'm slowly reducing the amount, was only 1 mg daily anyway, I'm at 3/4 mg now and getting ready to go to 1/2. You should NEVER stop meds that affect your central nervous system. As for your issues being a side effect of that, my internal vibrations, which I've had since 2019, stopped for a week and a half after I did a sleep study wearing nasal mask. I have mild sleep apnea, my pressure is set lowest it will go at 4, and now have the machine that I wear nightly BEFORE I go to sleep. It has helped tremendously. The ER nurse did ask if I'd been tested for covid or had covid because the issue with smells seemed to be the new thing with that. I said no to either and had a covid test. It was negative. Hope you get your problem straightened out as I'm still trying to figure out the cause of these vibrations.
