Hi Ian,
Thanks for your reply and pun appreciated/forgiven!
I wasn't necessarily expecting to have the Tadalafil tablets in my discharge pack from the hospital pharmacy, as I wasn't sure how nerve sparing had happened. Regardless, I just got on with taking them and whilst I can't say any erections have taken place, I can feel some activity down there! Maybe it's my imagination, who knows?
Hence posting my question about getting a repeat prescription. My (telephone) follow up with Urology has been booked for 17/9, so I'll certainly ask them more then as well but, thanks to the advice from Kev and Andy, I've just emailed the consultant's secretary to ask if he can contact the GP.
Good luck with your recovery and hope the Tadalafil works for you when you get it! Keep us in touch with your progress..
