This is my first post. I've been on Decapeptyl ( and HRT) since March and have been really tired- like no amount of sleep is enough. Had my first Prostap injection recently to see if I felt any better than I did on Decapeptyl but the tiredness has hit me again. My endo symptoms are better but I'm too tired to enjoy that. It's starting to get me down. Has anyone else got experience of these injections?
