ive read quite a few articles about post workout shakes. most of them push either carbs only or a carb protein mix. one article in particular from John Berardis site reckoned you should have a carb protein mix of 2:1.
even a serving of pro-recover is about 45g carbs and 20-25 protein.
so if you can take a big blast of simple carbs what about a chocolate spread sandwich or something. I know Kerry used to eat a bag of jelly babies post workout. seems like a cool idea to me
