@lisalucier @darkelliam I really can't imagine why it would happen, that on days you exercise you can't sleep. My immediate thought was that you were exercising too close to bedtime, I know that's a problem for some. You said though that you exercise in the morning so
you can't possibly be wound up by bedtime. I wish I could suggest some cause but I am stumped. On days when I exercise I find I am generally more tired at bedtime and can get to sleep more easily.
