Slimfast is high in sugars, so I would avoid that for sure. In case you haven't heard of adaptogens, they are a category of herbs that help the body deal with stress, restore balance, and support normal metabolic processes. (A lot has been discussed recently about adaptogens, even Oz on Oprah). Often times stress causes us to overeat as well as produce excess cortisol (causes the body to store fat, esp. in the belly region). Adaptogens support weight management by regulating blood sugar, insulin metabolism, and cortisol levels; aid in digestion; and increase energy. In fact, adaptogens have the ability to shift the body's metabolism to a greater use of fat for energy.
To learn more about fast acting adaptogen sprays (Slim is wonderful for cravings and weight control) and watch "The Story of Adaptogens Documentary" 10 minute video, go to VitalHealth.TunguskaMist.com
You'll have more energy and endurance to work out with adaptogens. I would recommend increasing the cardio and continue with some serious weight training. Lean muscle mass helps speed up your metabolism, thus you'll burn more calories! Avoid fast foods, processed foods, and all soft drinks, (if you're not already). Drink plenty of water and eat smaller portions throughout the day. It sounds like you're off to a good start already with diet and exercise. The Slim will make a huge difference in reaching your goals faster. Not to mention it's got a money back guarantee!
2 great books that I recommend are: Living Lean, by Larry North and Adaptogens: Herbs for Strength, Stamina, and Stress Relief by Winston and Maimes.
