Wow! That's very interesting, and somewhat unnerving. I was prescribed, at one point, 1 mg Xanax (alprazolam) to be taken 5 to 6 times daily (as needed) and never had any problems. But, I was given the somewhat high dosage when diagnosed with "severe anxiety disorder". My mother (the subject of the initial inquiry has undergone electroshock therapy, so I'm guessing that might be what merits the higher dosage.
I'm very sorry for not being able to accept your second response, but I am short on funds. I DO APPRECIATE YOUR HELP, though.
And, thank you VERY much for taking the time to try to help me (us)!
I wish you all the best in the future!
