I second everything Doozer writes.

Last summer I had a routine going of feeling a little better every second day. When I felt better I did more, which made me worse the next day. And when I felt worse I rested, which made me better the next day. It went on like that for two weeks or so, before my reduced brain managed to see a pattern...

Now l can sometimes recognize migraine triggers if I take a break and evaluate how I'm feeling. However, to do that I usually need someone to remind me. Other times I end up overstimulated without realizing it, and have to be told to go home or rest. It's kind of embarrassing sometimes, but far less bad than getting exhausted all the time.

So my best tip is to ask for help. Sometimes it is very hard to think straight while exhausted, so your family and friends (the ones that don't just tell you that you don't look ill) might be better at recognizing triggers and signs of overstimulation.
