My doctor suggested that I keep a health journal to help determine when I need extra medication. It has really helped me. Simply write down when you feel tired, anxious, or any other problem. Put in the date and time and any circumstances- what you have been doing, exposed to, eaten, emotional stress. See if there are any patterns and discuss your observations and questions with your doctor. This gives him more information to help you adjust your medication.
If I do not have enough cortisone "cover" I can become anxious and exhausted when I experience any sort of stress such as exercise. One of the reasons is that my blood sugar will drop which causes anxiety. If I need to do more than usual such as a few weeks ago when(I walked half a mile around a bird refuge. then I need to take a little extra hydocortisone about an hour before I exercise. (2.5mg to 5mg of hydrocortisone) I also usually need to eat a high protein snack before and after exercising such as nuts.
I have been avoiding chemicals for several months and am feeling much better. I have a lot more energy now. I am also more even tempered. When I am around perfumes or other chemicals, I become very depressed. It takes a few days to feel better and about two weeks to feel like myself again. Though I'm not going IN anywhere, I'm thoroughly enjoying being OUTSIDE.The fewer stresses I have in my life, the better I feel. Keeping a journal has given me an understanding what is a stress to me. It really has helped me live a happier life.
