"i started out valium for about 20 years 10 mg x 4 a day. used for anxiety and sleep. it worked was a comfort to know most of the time used 2 per day so i always had extra. i think knowing i had extras help almost as much. then dr changed prescription to alprazolam 2 mg tablets 4 times a day, some heavy difference, at first it worked well . in the beginning i felt it 30 minutes after i took it and only needed 2 per day, now i&#039;m at 4 per day that&#039;s 8 mgs and i don&#039;t feel it , i don&#039;t know about withdrawals but i hear it&#039;s pretty hard to get off and i&#039;ve been on them for 30 years. not sure what to expect but think i would feel more alert and energetic too"
