I recently did something like this. Although I only gained about 10lbs of muscle in a month. I quite drinking soda, started drinking water and grape juice instead. I also took muscletech's Nitrotech and Celltech. I lifted 4 days a week (about 45min at a time) and would do cardio type workout 1 other day a week (about 30-45min). I'm glad that you posted this to your blog instead of trying to sell people a book or something.
