The B vitamins
and minerals help nerve function, specifically B
12, and magnesium, potassium, and sodium. To get those nerve foods, you should eat beef, milk, cheese, eggs, nuts, seafood, enriched whole grain cereals, dark leafy greens, potatoes and tomatoes. Smoking also depletes the Vitamin C in a person, so to restore that, for a while consume lots of citrus fruits like orange juice, plus the nerve foods potatoes and tomatoes.
