The blunting effect is common, and a major complaint with meds... For me I had broke up with my gf as soon as I started taking Lexapro. Were back together, but I have trouble feeling passion and love for her like I used to. Things may have faded and this is just normal, hard to tell. One thing that helps some is to add a medicine like Wellbutrin..

Your sig says you have Schizophrenia, so I think this would be a bad idea as it increases the dopamine level in your brain. I would ask your pdoc.. you can try several different meds till you find one with less blunting. SNRIs are sometimes less blunting than SSRIs for some.
