The first few hours after O are ok, sometimes I even feel good for a little while. within 6 maybe 12 hours I notice the symptoms setting in. They get progressively worse until day four when they peek, and subside through day six and seven. Sometimes when it's really bad on the fourth or fifth day, I end up masturbating just to get a way from the pain and psychological symptoms for a little while.
I used to have a odd experience for an hour or two immediately after orgasm, that I felt great, energized, focused, motivated, knowing exactly what I wanted and needed to get done and exactly how to go about it. I don't experience that high anymore.
