Anje - I think protein is a very good idea if your body says so. I've had quite a lot of meat cravings while in plaster, although interestingly now (presumably) that after 7 weeks the main healing process has finished I'm feeling much less carnivorous.
A good steak is the answer to many a problem, anyway, I find.
DavidG1 - sorry about the 1970's rocker reference, mate! I thought you said somewhere you were middle aged?
