The Ireland centre has been installed as favourite to regain the post he filled in New Zealand eight years ago following his starring role in Saturday's 30-22 RBS 6 Nations victory over Wales.
"There's more chat about the Lions now, more column inches. Every week there are new Lions teams for that week," he said.
England's visit to Dublin this weekend offers another opportunity to see off a rival at outside centre for the Test series against the Wallabies, with Manu Tuilagi his likely opposite number eight days after Welshman Jonathan Davies was outclassed.
High praise greeted his performance in the championship opener at the Millennium Stadium, but O'Driscoll is far too seasoned a campaigner to take notice of the shifting sands of armchair Lions selection.
"You're not even flavour of the month now, you're flavour of the moment," he continued. "It's not just one month on, one month off, now this is happening weekly and daily. You're in the frame, then you're gone, forgotten about.
"You have to take it all with a pinch of salt. I like to think I am a decent judge of whether I'm in the mix or not.
"It's a huge honour to be a Lion - among the top 35 players in the four nations.
"It is definitely an added incentive in the Six Nations in a Lions year, so you get your performances to as high a level as you can."
