I used to have a GREAT memory until about 21, (now 43) when I started a pedal bike store. It was at that time that I started taking benzodiazapenes. (And also lots more stress due to my bike store. Imagine, a social phobic in retail. Did I take a beating!!!) Sometimes I wonder if it is the medicine, but realistically probably my severe anxiety is the culprit. It's weird in that I can remember numbers, such as that of the parents of my college roommate, but at times have trouble remembering my brothers wife's name, or if I took my medicine in the morn. Just recently I was at the vet and the receptionist asked me, after my appt., what the follow-up would be with my dog. I could not remember.
I notice that when my anxiety is worse, also then my memory is correspondingly worse.
