I was taking 2, one in morning and one at night. After noncompliance with a substitute physician not filling script as she said she would, I went into withdrawals. It was horrible. Went to hospital 2 times within a 24 hour period. Tried to tell them that something neurological was going on. Everything smelled like cheap men's cologne. Threw out milk because it smelled bad. Did not eat for 5 days and PHYSICALLY could not sleep for over 48 hours. It was simply horrible. It was my sister, who is a doctor, that asked me when was the last time I had my xanax and I said 2 days ago and she said Carol you're having withdrawals you need to get that medicine ASAP. Finally got the nurse manager to call them in. Within 3 minutes of taking that pill I was back to normal. I then started with 1 in the morning and a half in the pm for about 3 months. I then went to 1 a day, in the morning, for about 1 month and then I did half in morning and half in afternoon. I am now at a quarter, half of a half mg tab. I have anxiety very bad but the quarter mg seems to work except when we have a severe thunderstorm or hurricane then I must take a whole one. So a 30 day supply actually lasts about 3 months. I also take hydrocodone for chronic back issues. Just had another MRI, last one was in 2020, and it shows changes. Internal vibrations are from a nerve being pinched in lower back that causes both thighs to go numb if I stand in one place too long. That's one reason I had to go on disability at 63, 3 years ago. I take my pain meds every 6-8 hours and have for over 20 years. They still do their job. I could easily go back to 2 xanax a day but since they are fast acting I can take them when the situation calls for it. I will never have withdrawals again.
