I am a server in a restaurant and I tend to work a lot of hours, although it varies from week to week. The shifts are long, about 9 hours if I am there all night, and you can bet that by the end of the night I am ready to fall over. But I don't excercise regularly, so I think the fact that I am walking around all night really helps me. I wore one of those little meters that counted how far I walked one night and I walked almost 6 miles! My last pft's were at 88% (but that number seemed a little high compared to how I was feeling) and I go on IV meds about every 6 months. My employer is extremely understanding of my condition. If I have to call in sick or if I ask to leave early, they don't ask questions. I kind of wish I had a 9-5 job, however, so that my days would have more of a so-called schedule. I could wake up at the same time everyday and get my morning treatment out of the way, go to work, come home and do another treatment. I think it would be better for me. The way it works now I miss a lot of treatments because I am at work until 1,2, sometimes 3 in the morning so by the time I get home I just pass out without doing a treatment. Then I sleep until the afternoon, do 1 treatment, and do the same thing all over again.
I guess in answer to your question, the way that I handle it is I don't take sleep and rest time for granted. I try not to have too much on my plate all at one time. When I need time off, I take it. I am lucky that I have managers that understand and recognize when I am getting sick.
