I have taken all three at one time...after my husband passed away. It was only for a short period of time though. It made a big difference for me. The Xanax and Zoloft I have been on for about ten years. A thirty day supply of Xanax lasts me a year. I am wanting off all of it though. Don’t need it anymore. The SSRI withdrawals are bad. Have to do it very slowly.
I was given a 30 day supply 6 months ago and still have some left. I use it very judiciously but I'm not ashamed to say I sometimes need it now like I did when it was first prescribed for me. Panic attacks are something I thought only other people got and even then I was arrogant enough to think you should just 'get over it.' I wouldn't wish one on my worst enemy and I really mean that.
