Panic Disorde
"Been on Effexor XR/ Venlafaxine ER 75 mgs. for a number of years now to damp down the panic attacks I began having at 3 am every morning (like clockwork) some time after menopause. Very effective at stopping the panic attacks once I got up to blood level (about 8 weeks). In between took Lorazepam nightly until the Venlafaxine kicked in. Due to intense itching and some hives, as well as fatigue, on the Venlafaxine.  I switch to 37.5 mgs. here and there for a day, which has helped. Killed my sex drive, however, and periodically have headaches."
