What are the side effects?
I haven’t taken Viagra or any of the generics for a long time.
It did give me a thumping head ache (the head on top of my shoulders), but the side effect I most remember was, for a day or so after taking it I would get a random erection. Sometimes it would appear at the most inappropriate moment

The hard on taking a dose gave me made my c!#k seem like a baseball bat, anyone on the receiving end would get battered.
