I had to call in fatigued for my West Coast flight. I was completely exhausted after my multiple early shows from my original pairing on two days before. I just came in from a very early departure this morning and by the time I got home; in a vain attempt to get some sleep during the day before my evening departure for the Coast; I was completely disoriented and exhausted. Being 'double pumped' or having multiple duty periods in one day is completely unsafe; but asking me to do a 5 hour flight to the West Coast and arriving at midnight Pacific Coast time the same day is completely unsafe.
A First Officer got home early in the morning and was scheduled for a five hour cross country trip that night but unable to get sleep during the day; called in fatigued for this second duty period of the day.
