the few days before this cluster of migraines, I was extremely tired. Sleeping all the time, napping throughout the day. I had no idea what was wrong. I felt so run down. I figured maybe I was getting sick, but I felt healthy. this went on for about three days, so I didn't think it was migraine related. Usually, if its a precursor to a migraine it last only one day. However, these things tend to get worse. I wonder if its my body's way of resting before the internal battle of the migraine.
