"4 years ago i had my first panic attack/anxiety. had hyperventilation and end up in the er. my doctor prescribed 0.025mg of xanax. i took the medicine as required. i wasn&#039;t able to drive and do anything out by myself. i was afraid and worried of being alone. i always fear that it would happen again. my thoughts are always what if...anxiety was taking over my life. i was able to control it for 2 years. just this month i recently panicked for no reason. my dr. put me on this just in case i have a full blown anxiety...but the downside to this medicine is it makes me really sleepy and tired. but it does works!"
