I have been taking .25 mg of Xanax for 13 days twice a day as recommended by my Endo chronologist because of anxiety I had with bad medication for my thyroid.

My question is how do I taper down for a minute I started two nights ago taking half of the .25 and this morning taking half of the 2.5 for the day and plan to do this for the next week is this OK well I have bad side effects. I am worried about it so I want to get off of them now can someone please advise thanks
