Getting good sleep is important when working, although I am not very good at doing that. During hypomania, I get into a workaholic mindset, where I feel super productive and fast-paced, but that is never sustainable. When depressed, I try to choose at least one point during the day, where I sit by myself, take some deep breaths, and regroup before getting back to what I was doing. Taking breaks helps me to a degree. Also, don't set your expectations too high, or that could cause burnout. Be realistic and don't bite off more than you can chew. Self-care is a must.
