Hi, if you could get h to go on a gluten free diet [by doing it together, but without much hoohaa] he might feel physically much better. I have virtually cut out wheat, and feel so much fitter, and have lost weight from places where it is hard to shift [butt and thighs].
It means two things really - one is eating less processed food, which often contains wheat/gluten, and subsituting other things, rather than for example eating gluten free bread [which I dislike]
I eat rice pasta [nicer than any of the others - corn and gluten free for example] and I eat oatcakes, and rye crispbread.
There are many oat based cereals around now. It is really bread and pies that are the issue, and while gluten free bread is boring [well, I think so] pastry made with gluten free flour, or better still spelt flour, is fine.
I would buy a light box, and have a 'light' alarm, which apparently are wonderful. Do it for you!! The benefits of wheat free are enormous, I promise. I have had people asking me what my 'secret' is!!
