And the Irish wing reckons he has some making up to do as he continues his glory charge alongside Ryan Jones, Shane Williams and Gavin Henson this weekend.
"It's been a huge weekend for Irish rugby and a hectic few days but it's great to be back with the lads in Wales," said Bowe.
"I know I will have to try and make some friends in the squad again and that's priority number one for me. The boys even made me sit on my own for breakfast!
"But if we get a few wins in the next couple of weekends, then it will round off a nice couple of weeks."
Bowe will have little time for celebrating when he plays for the Ospreys against Gloucester in the EDF Energy Cup semi-final this weekend.
And the Lions hopeful insists the historic sweet taste of Grand Slam success is only the beginning as he chases a treble with Sean Holley's men.
"I've had ups and downs in the Irish jersey so (it's great) to be part of something so special. It has not sunk in probably but it's an amazing feeling. I feel so proud," added the 25-year-old.
"But, of course, I can reach that peak again as a rugby player. This season has the potential to only get better.
"The Grand Slam was enormous but we can win all three competitions with the Ospreys. It would be unbelievable."
Bowe is coming back down to earth with a bump after a whirlwind time since his second-half try in Cardiff carved his name in Irish rugby folklore and his cult status grew with a rendition of 'Black Velvet Band' on the return to the Irish capital.
"The reception was surreal. We were greeted at the airport and there were thousands of people on the streets of Dublin. It was nice to give the Irish public some joy and happiness."
