The Neath second-row felt the 30-22 defeat in Rome as keenly as anyone, and admits that morale must be lifted before Wales are thrust back into the limelight.
And Llewellyn admitted the white-hot atmosphere of a RBS 6 Nations clash with England in Cardiff will come as a welcome relief compared to the ferocious reaction which has followed the Italian defeat.
He said: "It is different these days, when we lost to Canada back in the early 90s we were able to pack our bags, go home and hide for a couple of days.
"These days we are in the public eye seven days a week and it is difficult to escape the attention.
"But as a side we have to forget about last weekend and realise that the defeat will not affect anything that goes on this weekend.
"It will be a different occasion and a very different atmosphere. There will certainly not be a problem for the players in terms of passion and commitment and I am sure the supporters will be right behind us."
"Yesterday's session was very impressive and very interesting. I think all of us got things out of our system and hopefully now we can have a good run in to Saturday's game."
