haha...I got the same deal about a month ago.
It's so so as far as N.O. products go. For some reason it doesnt provide the pumps that I've gotten out of some other N.O. products (i.e. SuperPump250 and N.O. Shotgun). The dizzy feeling is most likely from the Beta-Alanine in the product which usually will give users a 'tingling sensation' after about 45 minutes of taking the product. If it's not a tingle, it could be the caffeine level is bit high and you made need to scale back your dose (i.e. 2 scoops to 1 scoop)
