What is the best way to stay healthy because i am working graveyard?

Shift work is: Difficult. Staying healthy means feeling good which means you may consider a medication for shift workers. Modafanil is the older but effective med, taken about an hour prior to the shift it works well. There is a diagnosis of circadian rythm disturbance, shift work type. Nuvigil is the newest med but is made from modafanil which will be generic soon. You may also need help with insomnia.

Look up: Circadian rythm disorder shift work type and look up modafanil, goes also by Provigil in us or sun modalert which is from india. Look up Nuvigil as well, it's newer but made from modafanil. It's a good drug, you may also need help with sleep.
