Actually I am having Lin's supplements from www.herballove.com & it's ok but takes time. Just some days before I came to know about the way how to stop wet dreams and finally found through an expert about semen retention. In fact it will greatly support my recovery as well. It is called "Anulom Vilom", a kind of Yoga which is one of the greatest way to save your semen from unwanted wet dreams. See the attached link below:

Guys who practice can see the refreshment from the first day of the practice.
Good Luck.
