I was on lupron and Erleada for 13 months with RP after the 6 th month. Being tired is normal and expected, however, these meds worked well for me. I am now med free and cancer free and hope to stay that way. If the cancer returns, I will probably go back on these meds. I recommend that you put up with this side effect and that you continue with these meds unless they cease to work or that your side effects change and become unloveable. Good Luck.
