depression
"20mg Citalipram was prescribed by my doctor for depression.  A few things, one of them maybe odd, that I've noticed over the past two years of being on it.

I felt queasy and had slight nausea the first couple of weeks but then that settled down to a nice sheen of calm over me or something. Very nice.  But I began having difficulty getting an erection or ejaculating strongly. I figured a permanent side effect.  The thing is that around 6 months later, I started having very strong erections and deep orgasms.  Much stronger than I've historically had.  When my doctor eventually decreased my dose to 15mg and now 10mg, orgasms are now much less intense.  It seems my side effects differ from others sexually."
