Latest update....after some consultation via phone and fax (I am on vacation, returning today), my urologist agreed to the 30/1 bimix. Franck's processed the order yesterday and sent it to me today, so I should receive it early next week.
Fingers crossed that it works for me without any significant side effects. I already have mild Peyronie's (since age 33), so I will be looking closely for that symptom, of course.
I think....knock on wood....that I can make sure to avoid priapism by starting with a very low dose. Of course, from reading posts here, it seems a low dose for some causes a multi-hour erection in others.
Any way, I am very excited and hope things work out ok....if not at first, then after trying a few different dosages to see what works best for me.
Thanks to all of you for your advice and support.
