utter - utterly
Utterly doesn't go with excited because if you are excited about something that is normally a positive emotion and both utter and utterly (meaning complete/completely) have negative meanings and are used only in negative contexts:
To say that we'll be landing on Jupiter in 2010 is utter nonsense.
If you think that, then you are a complete and utter fool.
To spend all day window-shopping, especially at Christmas, is an utter waste of time.
They had no means of support and were utterly dependent on their parents.
To suggest that there should be a total ban on smoking is utterly ridiculous.
complete - completely
Complete and completely are much more neutral and can be used in positive, neutral and negative contexts:
However, despite the flexibility of this adjective/adverb, we cannot say completely excited.
One of the hallmarks of a proficient language learner is knowing which adverbs collocate with which adjectives.
So, which adverbs go best with excited?

terrible - terribly
One of the most common adverbs used with excited is terribly.
Note that the adjective terrible (meaning horrible, dreadful, awful) can only be used in
negative contexts but the adverb terribly can describe extreme behaviour in both negative and positive contexts.:
awful - awfully
What's wrong? You look terrible. ~ I'm in terrible pain.

Children in Britain get terribly excited on Christmas morning when they come down to open their presents.
Note that awful and awfully follow a similar pattern. As an adjective, awful is used only in negative contexts, but as an adverb awfully has both negative and positive meanings:
It's an awful shame that she's unable to come back home for the holidays.
She was late and I was worried that something awful had happened to her.
He was awfully drunk. It was an embarrassment to have him there.
He may get on your nerves, but he has always been awfully nice to me.
She's awfully pretty, don't you think? The most striking person in the room!

Note that awesome, meaning very impressive and sometimes a little frightening is a favourite adjective used by young people and people in the media currently:

It was an awesome party. We danced all night and then watched the sun coming up over the sea. No better way to welcome in the New Year.
