I Have Prostate Cancer, Found Out Sept. 2014. Have Been

I have prostate Cancer, found out Sept. 2014. have been taking Lupron shots every 6 months since then. It had metastasized to my sacrum and lymph nodes. Had an MRI 2 mos ago and the spot on my sacrum was gone. Had a CT scan yesterday and it was very good, no masses seen anywhere. PSA was 22.5 last September, with a Gleason score of 9. Since I started taking the Lupron shot PSA dropped to .3 and .4 till this last Oct and at that time it rose to .6 and yesterday it was .8. feel good, no problems other than having to urinate very frequently. What is you suggestions?
