Trapper, can you give me specifics on the supplements?

Thanks Trapper,
Do you know how much of the B, selenium and C I should be taking. I am taking 1000mg of C a day unless I feel any detox symptoms and then I take 3000. I do take a B-complex vitamin (I think B-50) but the only selenium I get is in my multi (powder shake) vitamin which is about 200 mcg, is that enough?
