Since none of my wife's uncles were stil lving, we tested 4 of her known 1st cousins to see if we could uncover the mystery. One of my wife's male 1st cousins is now showing as a Close family - 1st cousin match and I suspect that he and the new cousin are really half-siblings.
Your healthcare provider will tell you how much VIAGRA to take and when to take it. Do not take VIAGRA more than once a day. VIAGRA usually starts to work within 30-60 minutes. You may take it up to 4 hours before sexual activity.
Ideally it is to be taken almost an hour before the sexual activity. However, Viagra can be taken anytime from 4 hours to 30 minutes before sexual activity. It takes 30 - 45 minutes for showing Viagra's effect and this effect lasts for almost four hours.
