Hulk,
Don't be in such a hurry to start a sack just yet. Try increasing your cardio, whats your present diet? If you have not ever had any heart diesease, high blood pressure or any history of a seziure disorder look into a dieurtic or some type of Thermogene type product. I personally take a product called Thermogene. It's cheap and it will really raise your basal metabolism. Don't take any of these after 12 noon as they may make going to sleep very difficult. I know this is probably not what you want to here but it is cheaper and it's worth a try before trying a stack.Good luck
