Hi Bill. 16 tabs 100mg monthly is double the NHS recommendation I think. So you are probably ahead of the game!!! My only side affect on the Sildenafil is a blocked nose and an aubergine face for a few hours. I too am on repeat prescription for the 100mg. I was only offered 2 months worth (56 tabs 5mg) for the Tadalafil - So we shall see in due course
I see you had one side Nerve Sparing same as me. I am very grateful for you saying that I am doing OK for 10 months as I am quite impatient on this subject probably because my mental age for this area is nearer 16 not 61 !!! I am also lucky to have a very supportive wife 15 years younger than me. I think looking back to discussions Pre-Op, I think I only really focussed on the "possible shortening of the penis" rather than the ED issues which in retrospect was an error in my judgement at the time. I would still have had the Op though.
I have used the pump daily for months now and this is the real improvement. I say "Improvement" and not "Erection" as a caveat.
Wishing you all the best.
