Hey there. Welcome aboard! Just a little tip, next time, you might want to use a Private Message.
To answer your question, if you have ammo, you have what you need for the time being. Try wearing 2-3 sprays. I like to put one on each side of my neck sometimes, for close contact, or one on each of my wrists, backs of hands or forearms, and maybe the third shot to my throat. See how that does you for a couple weeks. Then send me a PM and we can take it from there.
