I pushed myself into a highly anxious state using dietary supplements with caffeine in them (I did stop them but it had already started things rolling) which fueled my spring hypomania . So though I don't think coffee in moderate amounts would be a bad thing necessarily, coupled with the lack of sleep it could become a problem, you just need to keep an eye on yourself. I agree with bipolarnurse about negotiating for better hours. I don't know if it would work in a business, other people here can say yes or no since I don't work, but when I had to drop out of student teaching because of my breakdown, my pdoc wrote a note to the college dean. He didn't specify what health problem I had but it worked to allow me to skip that semester and do my student teaching the following one. I don't think he wrote his md specialty in the note. Let's see what other people think of that idea, I could be way off base.
