"i have suffered with anxiety and panic attacks for years. it got so bad i would actually be driving, pull over to the side of the road and call 911 because i thought i was having a heart attack, it was really scary. i&#039;ve been on xanax for 10 years off and on. i take 0.5mg once a day when i start feeling anxious and my insides feel out of control. it does frighten me to think i could be addicted to this medication, but on the other hand if it relieves my symptoms than i guess i need to take xanax as needed."
