I'm 5 1/2 months post surgery and been using the generic Viagra from alldaychemist since day 10, with absolutely no results to show. However, it takes time to heal and reconnect nerves, as others has said, and using the generic is to be considered a rehabilitation medication until such time as the nerves repair and you start getting results from the pills. The purpose of the generic is to keep allowing the continuing blood vessel conditioning (use it or lose it), so when the nerves do start working, you will not have an atropied penis and blood vessel system that can't respond now that the nerves are working again. Just consider it as rehab and preventative medicine for now. When you will regain function with erections is anyones guess, but keep working at it until it comes. If you haven't already got one, I suggest you look at a penis pump to help in further infusing the blood vessels and compartments in the penis with blood.
I did get the flushing and such with the 100mg dose but none with the 50mg one.
