Hello and welcome to Healthcare Magic. Thanks for your query.
7 tablets a day of Xanax
is definitely excessive and indicates that you have developed an addiction / dependence on the medication. You must remember that long term use of benzodiazepines, like Xanax can result in "tolerance" to the medication - which means that progressively higher and more frequent doses will be required to produce the same effect.
So, increasing the dose is not only dangerous but will just push you into more dependence. I would advise you to consult a psychiatrist
for further help in coming off the Xanax, and planning other treatment strategies to tackle your chronic pain
Wish you all the best.
