So in the last week, I've had p s a result which was good <0.01 at 16 months post op, I've also, yesterday, been to see the lovely Wendy, my E/D nurse who has altered my script. from a daily 50mg sildenafil to once a week 20mg Cialis tadafil, in the vain hope that I may gain the missing 20% of my erections,20mg is the highest dose available, but apparently this drug can continue to work for up to 36hrs. I am wondering if any of you have tried this and what results you got? I'm sure my mate Lyn will know something of it, Wendy did mention Levitra, but said better to try this first, she does seem quietly confident so I'm happy to give it a go. Diesel x
