"i&#039;m a 19 year old girl and i&#039;ve been diagnosed with anxiety for a long time but never had an anxiety attack until now. my doctor prescribed me this medicine yesterday after i told her i had an anxiety attack 1 day ago. my heart was literally at a speed of 100 but she gave me medicine to slow it down. it really helped me sleep last night too. this medicine took me about 30-45 minutes to kick in and then it knocked me out and i was fast asleep."
