Yea Just Wondering I Know There Have Been Other Posts

Yea just wondering I know there have been other posts on this subject. What is the best way to cure premature ejaculation? There are son many products out there, which I admit I have tried a few but none of them worked and some had side affects such as headaches, upset stomach. I would like to find something that works fast (not having to wait 30 days or so), something to use a natural herb etc. Does GNC have something that can help prevent premature ejaculation?
