I'm sorry but I don't have any specific recommendations for you. Have you tried visiting a health food or supplement store? I would think they'd be able to give a few ideas. Your doctor may have some suggestions for you as well. Good luck! I hope you find something good- I know that some of those aren't the best tasting!
The only protein powders I know of that aren't soy based are either hemp or wheat. Your best bet is either your local health food store, co-op, or Whole Foods.
