"i&#039;ve been through a lot of loss in my life. not quite sure if that&#039;s why but all of a sudden horrible panic attacks ! i also have equilibrium problems i can work and do most normal things but it&#039;s still a pain. my primary care prescribed this to me about 4 yrs ago. i love it. it definitely helps but now instead of a half milligram i am taking a whole once a day. but i guess my body has built a tolerance.
