I am the same way. Not sure if I have gotten much of an effect either..but I continue to take it.
I have been taking Green Tea pills that promote 315mg of it..not sure how that translates into what you get from drinking an 8oz cup.
If taking Ginger or drinking Green Tea gave people viagra like effects...well those companies would be going out of business

because you probably couldn't keep the teas on the shelf.
"In other news, supermarkets can't keep stock of Green Tea. Labor workers in various countries have been forced to work extra long hours in the mountains collecting tea leaves. Green tea is being sold on the black market, being stolen at supermarket drop offs, and more. Green tea is the new viagra with no side effects!"
LOL
I am coming up on 5 weeks of the 5 G's, and just not sure I have noticed any form of a night/day effect . Maybe I have gotten a little improvement. Between sex and masturbation..I might be getting off too much to really notice LOL.
