Thanks so much for your replies. I haven't decided which I want to try yet, but my doctor said, try one OR the other, to see if it has any effect.

A woman my friend knows have taken Glucosamine for some time now, she was almost on crutches, but is walking without problems now. I think I'll have a chat with her.

I really don't like taking any kind of medicine, if I can avoid it, but I do take a Calcium/Vitamin D every day and the occasional 1/2 sleeping pill if the 6 young people upstairs are driving me crazy with their noise - and if I have an important meeting the next day.

Anyway, I guess fish oil won't do any harm.
