Story in the paper that says consumption of green tea can inhibit the effectiveness of certain drugs, dealing with blood pressure, ive noticed that when using Viagra, black tea gives better results than green tea. To be honest only drink green tea cos it stains less than black tea. Anyone any views on best drink to take a Viagra with? I reckon it works more quickly with a hot drink, but read that coffee dilates your blood vessels, I presume this is a bad thing for someone trying to get a hard-on.
