[QUOTE=Kenal1;6877229]I also get the headaches, flush face, etc but, usually, 2 or 3 Tylenol solves the headache problem. My understanding is that the generic form is identical to the real thing and, as such, the real Viagra would cause the same symptoms. Am I wrong about that? I've never used Cialis. To you guys who use it, what, if any, side affects do you get?[/QUOTE]Sounds like too strong of a dose. Try backing off and taking half.
