Whey is a fast digesting protein source and is a great choice post workout. I have read that fructose, the sugar found in fruit, will not restore muscle glycogen, but will instead replenish glycogen in the liver. You are basically looking for any carbohydrate with a high glycemic index. You can order dextrose cheap online, something like 5 bucks for 2 lbs. Yes, after letting your shake digest, eating a meal such as tuna/oats is good. Hope this helps.
