"i started taking xanax over ten years ago for my anxiety. i started with .5 mg twice a day and ended up at .5 mg every 4 hours and still felling like i needed more as i was addicted. i had one heck of a time weaning off. i now take 1/2 of a .25 mg tablet every 3 to 4 hours when needed for my tinnitus. it works to lessen the anxiety caused by the constant ringing in my ears and i try some days to take it only once or twice. it has worked great for me but i suggest being very conservative with your dosing because it is very easy to build a tolerance and form an addiction."
