Hi, sweet Robert. You know, I think the two do go together, at least from what I've read. When you work night shifts, you interfere with your body's natural circadian rhythms, which are the signals your brain sends your body for sleeping and waking. Those rhythms are messed up when you're working at night--and also when you're working long hours. People can get anxiety, depression, eating disturbances, sleep disturbances. All sorts of natural functions are disrupted.

Any chance you could get a day job instead? I hope so!
