For example: one morning my neighbor asked me to turn off her sprinkler in the PM. When I left my house in the PM I drove right by her house, and found myself glued to looking at her place! I slowed down and asked myself, "Why am I staring at her house??" But nothing came to mind, and I drove on by. Later she called & asked why I hadn't done what I'd said I'd do?? I just heard for the 1st time that Lithium can cause memory problems. I take Lithium, 300mg 2x/day (for about 20 years), and Effexor XR 75 mg. (for about 10 years)
