Brian O'Driscoll is doing everything in his power to ensure he is in tip-top shape for tomorrow's crucial Six Nations match.
The Ireland captain wrote on his Twitter that he would even be trying a new sleep app on his iPhone to ensure he gets a solid nights sleep in preparation for Ireland's match tomorrow.
"Going to try my newly downloaded sleep cycle app on my iPhone tonight. They really have all bases covered don't they?" he wrote.
After Ireland's crushing defeat against France two weeks ago, the team are in fighting form preparing to battle England at Twickenham tomorrow.
The match is being interpreted as the team's chance to redeem themselves after their loss two weeks ago.
The team are staying at a nearby hotel in Chiswick, as Paul O'Connell explained on his newly formed Twitter account.
"Moving day. On a flight to London and off to our hotel. Never stayed in Chiswick before," he wrote.
Although neither went in to detail about any additional preparations they will be taking before the big match, team-mate Ronan O'Gara was still reeling from their loss last week.
The Cork native struck back at columnist Kevin Myers for blaming him for Ireland's loss to France.
The Munster and Ireland star admitted that although it "takes a lot for me, as a professional sportsman to react to a newspaper article", he felt the criticism was so scathing that it demanded a response.
O'Gara (32) said: "I do not and will not accept being castigated by a journalist who I suspect knows nothing about rugby, but somehow appoints himself as an 'expert'."
The Irish Independent columnist wrote about his belief that the Cork native was a "weak" player.
"Declan Kidney did not choose a team that could win. His selection of Ronan O'Gara said as much," he added.
However, O'Gara said that his description "falls well short of the journalistic standards I would expect from one of our main national newspapers".
