Greetings, Theo. My doc has a schedule for everyone on PSA tests and seems to stick to it. Every 3 months for 2 years, then every 6 months for 2 years and annualy thereafter assuming everything stays good. My doc always asks me how I'm doing and if I have anything I want to tell him. You might just bring up to your doc the idea of doing another PSA in 3 months rather than waiting 6 months.
As to the cialis, my doc said he wanted me to take either cialis or levitra and gave me samples of each. Shortly after my catheter came out I was able to get about 70 - 80 percent erections and so didn't take the meds (I did call and talk to the nurse, but not the doc - should have talked to him). I never got above that 70 - 80 percent level and in fact started to regress. As soon as I started to take the meds 2 times a week, I was at 100% of presurgery firmness. Bottom line for me, if I had it to do over again I would have followed my doc's instructions and started the meds right away.
Glad things are coming around. Look forward to continued good reports. David
