Thats it 
In particular the herbal remedies/vitamins I could go into a lot more detail on, to help decide which you would most benefit from.
where do you live? Do you have a good health shop, where you could get good advice? (and I dont mean holland and barret who rarely seem to use trained staff or give good advice or sell good quality IMO)
Could you print this out and bring it along with you?
your nutritionist will be able to expand on the food side of things (I'm a nutritionist too
) but will probably be unlikely to know much about the herbal remedies(hence my suggestiuon to look for a good health shop)
hope that helps, at least its a starting point, perhaps you could google some of it?
