I took Casodex for two weeks prior to and two weeks after my first lupron shot. It was to prevent the tumor flare associated with the lupron. There are a couple of options for HT or androgen blockade. You can be on one, two, or three drugs. My own was a single anti androgen, lupron, similar to the eligard. I suspect that since you are showing mets your doctor has included the Casodex. This is common. A third drug is Proscar or Avodart if needed for further testosterone suppression. The Proscar or Avodart help suppress the dihydrotestosterone. There is at least one person on this site that has had extremely good results with the combination therapy similar to yours.
The tired feeling is a consequnce of the low testosterone. Best remedy I know is to get into a regular exercise routing. I know that helped me get through it. Still got tired but the workout seemed to revive me. I don't know about the headache but I believe the execise will help that too.
Good luck with your treatment.
