Ok I messed up. I had remembered something I'd read by CT about fat loss involving Surge but I remembered incorrectly. It wasn't cut out Surge completely but to reduce the serving size I got mixed up on. He says:
Rely on Surge post-workout without exceeding the daily carb allowance. This works best for relatively lean individuals (15% or less) since their daily carb allowance is higher. For example, someone who's 210 pounds at 15% body fat could ingest as much as 75g of carbs per day.
One full serving of the new Surge has 49g of carbs, so technically one can ingest as much as half a serving split pre and during workout and one full serving post-workout if he doesn't consume any carbs during the day.
However, it might be "safer" to use half a serving split pre and during and another half serving post-workout. In that case I'd add 10-15g of glutamine to both drinks to compensate for the decreased carbs.
Sorry for the confusion!
