ccpt, post chemo fatigue is a common issue that I have suffered. I find that I just have to take it easy when I get tired and not try and do too much. Since I have a desk job (engineer) for the most part at work it is not a problem for me, but it does make things around home harder so I have to plan extra time to get things done.
I have also had insomnia where some noghts I don't sleep at all and then the next night wghen i sleep it is hard to get up. My Oncologist has recommended Benadryl which helps some. I also find that if I try and keep a regular sleep schedule it helps but I still have problems sometimes. Good Luck and let us know if you find any thing that works for you.
