Global Patient Feedback for Viagra (Sildenafil) ( Post a comment )
Question/Comment:
It doesn't work for me at all..what a waste of money ($80 for 5/6 pills.)..and my script plan doesn't cover it. It's a rip off for most. Many males I know who have taken Viagra have had the dreaded 4 hour erection. Too many side affects..and age,weight,high BP, Diabetes...all play a role in how well it works. MHO...take it off the market...it's too risky for most men to take.

Question/Comment:
Alcohol consumption can definitely interfere with Viagra. Last week, three glasses of wine rendered the pill virtually useless. And me.
