I have all the common PFS symptoms. Brain Fog,Flat, emotion less, lay in bed all day staring, no motivation, no libido, no erections, numb **** etc.
HAve been like this most of my adult life, I did take accutane aged around 16 and maybe my life has sucked since then (39 now). I have up and down periods, not all awful. Have relied heavily on Viagra but doesnt work so good any more.
Something to be aware of, and I think this would apply to most "flat emotion type" PFS sufferers, is how getting all the emotions "normal" people have (back) would be extremely overwhelming and might cause anxiety in many of us.
I've had PFS for almost 2 years now but I can clearly remember how intense life was with all the emotions and androgenic drive (including ego, wanting to be accepted/liked etc). Suddenly getting all of this back would undoubtedly be extremely hard to handle too.
