Does (son of) God eat food and fall asleep?

It's not like that!

You are Satan's son, you eat and drink, in the end, you will end up waking up in hell! ù__ù

yes, he did that when he was on earth

That Q only makes sense if it's in the past tense - "Did the Son of God [Jesus Christ] eat food and fall asleep?"

While He was on Earth for less than 35 years, Jesus of Nazareth was fully human and had bodily needs with regard to food, water, and sleep. The Bible gospel accounts show that very clearly, so why don't you read one of them?

Yes, absolutely He did - He was God in a body of flesh. In the boat where the disciples were, Jesus fell asleep and when the storm came up the disciples were terrified and woke Jesus up to save them.

Also Jesus ate broiled fish, bread, herbs and honey on the beach when the fishermen (disciples) caught fish.

You don't read God's Word do you?

Since all gods are myths your question is moot.

At the time of annihilation God is eating up the whole universe and after that He'll fall asleep for a very long time, and when waking up, the whole of creation will start again

"Christ the son of Mary was no more than a messenger; many were the messengers that passed away before him. His mother was a woman of truth. They had both to eat their (daily) food. See how Allah doth make His signs clear to them; yet see in what ways they are deluded away from the truth!" (Quran)

When He came in the flesh He did. He received an imperishable body upon resurrection and no longer needs to eat or sleep, but can if He wants to.

God doesn't have children, God never begets nor was He begotten and God never sleeps, never has needs. God is without needs.

In human form, on earth, yes.

In heaven, no.

No needs there.
