The Taoiseach, Brian Cowen, is due to hold further discussions with his fellow EU head of states in Brussels today on how to respond to Ireland's rejection of the Lisbon Treaty.
Mr Cowen has described yesterday's talks as "very good", while his spokesman said Ireland needs time to reflect.
The Taoiseach is expected to present a roadmap for a way forward at the next summit in October after his EU colleagues effectively said it was up to Ireland to devise a plan following the Lisbon vote.
The other EU member states plan to press ahead with ratification and the European Commission has all but ruled out renegotiation of the treaty, even though it cannot come into force without Ireland's approval.
There is speculation that the current mood favours a second referendum in Ireland in the hope of overturning the 'No' vote.
