i took 50 mg
zoloft for 9 yrs for panic disorder, which worked beautifully. i switched to 37.5 mg effexor xr because of my decreased libido. after several months, i feel generally anxious again, as if i've had caffeine. the other thing i've noticed is a decreased memory for names, places, etc. can you tell me what is causing this, and how can i get relief from this anxiety? it makes me irritable and otherwise unable to function optimally. i am 49 yrs old, and female.
