ok.
Well for 1. Trying to fed your snake everyday since it refused food WON'T help!!!
If your snake refuses an offering, STOP, leave it alone and try again a few days to a week later.
Secondly, all these people are correct, your snake will not die from starvation as snakes can go quite some time without food. But you MUST have someone give it fresh water and check on it if you will be gone more than a few days....
Third, we read your post the first time when you mentioned it has never done this before, that has nothing to do with it, and great feeders sometimes go off food too. It doesn't matter how much, when or why he ate in the past.
He may be shedding and he doesn't want to eat or any number of various reasons. But trying to make him eat constantly everyday will stress him out more than not having a meal for a few weeks would.
If I was you, and I was going on a trip for a week or so, and my snake was refusing food, I would RELAX, get someone to check in on him and give him fresh water and paper, and then try again when you return home. This should give him the time he needs to rest, relax and get hungry.
