50mg zoloft at night and xanax as needed for anxiety Doc is thinking of weaning off the xanax as i have been on it for over 2 yrs and is trying what he referred to as an "old" medicine, Inderal which was originally rx'd as a high blood pressure treatment but the side effect is slowing of the heart. It definitely works on anxiety/nervousness (40mg twice a day) but am concerned about it dropping my bp too low (also take lisinopril for hb) anyone else taking this medication (for anxiety)?
