Andrew; I da know its not specific in nature it's just kinda a tiredness and a slight over all deprssion. I have also for the first time lost my libido and this is real different for me al together. I also without some effort or viagra don't have any erections. Im still undecided about the estrogen or the testosterone issues. So all in all it's one day at a time. One step at a time. Thanx Scottie
