The effects of chronic stress are serious and include heart attacks, cancer, colds, chronic pain, and even obesity. When your body is uder stress for a prolonged time, proper nutritional supplementation is critical to ensure your body functions, heals, and defends itself properly. Studies show that stress depleted adrenal glands can be supported and returned to optimal function by supplying them with nutrients.

In these cases, I recommend a good multivitamin program that includes vitamin C.

The B-vitamin complex is good for stress.

Also, Omega 3,6,9 supplements are known to reduce cortisol levels. That's a hormone that is released by the brain during period of stress, and which can interfere with sleep.
