Plus depending on what type of bi-polar or other mental disorder you may suffer from that can also influence you.

For example I was on a 7 year manic cycle from 1985 to 1992 and I did the work of about 5 people and felt like I could do anything! It was the most consistently successful I was at my music also!

But at the same time I did some serious damage to myself going 2 to 3 days a week without sleeping .........

@moose - I find that if you manage the workload and be realistic about how much you work you may find you can hold on to your job - Good Luck!
