She said of her week: "It's been a pretty heavy couple of days", admitting to the Mail that when she went up to her Downing Street living area late on Wednesday the first thing her husband Philip did was to pour her a whisky.
British Prime Minister Theresa May is fighting to save the draft withdrawal deal ahead of a vote in parliament after ministerial resignations and open talk of a challenge to her leadership followed its endorsement by cabinet.
Under the withdrawal agreement, the United Kingdom remains in the customs area for who knows how long - free trade deals can take years - while giving up its power as an EU member to shape the rules under which the European Union operates. "It would not. That issue is still going to be there", she told the Daily Mail newspaper.
The PM confirmed too: "I'll be going back to Brussels [next week]".
If 48 (15% of) Conservative MPs write such letters to the chair of the 1922 Committee, it means the party has lost faith in May's leadership and a new leadership contest must be triggered.
At the moment 24 Conservative MPs have publicly admitted to sending letters in demanding a change of leader, the most recent of whom is Richmond MP Zac Goldsmith. Brady told BBC Radio on Sunday the 48 threshold had not yet been reached.
She is a longstanding ally of May's and has said she supports the proposed divorce agreement with the EU.
Mrs May said the backstop is an "insurance policy", adding: "Both sides can say yes we agree that there are arrangements in place, that a deal that provides for the people of Northern Ireland and therefore that backstop is no longer necessary".

"The focus this week will be on the future relationship".
The DUP's parliamentary contingent, meanwhile, have said they will not support the proposal because of the "backstop" conditions.
Prime Minister Theresa May said Sunday she would return to Brussels this week to hammer out Britain's future relationship with the European Union - and overthrowing her would not help negotiations.
"The withdrawal agreement we have been presented with is unacceptable to Leave and Remain voters alike".
"I will be going back to Brussels", May told Sky News television, saying she would meet European Commission chief Jean-Claude Juncker.
Simon Kempton of the Police Federation, a union for police officers, said a "no-deal" Brexit could spark protests, and "it's a real concern that those protests might escalate into disorder".
Leadsom told Sky News Saturday "there is still more to be done" to get "the best possible deal for the U.K." before the draft withdrawal agreement is signed off on November 25 in Brussels.
After the Prime Minister unveiled her Brexit plan to cabinet ministers, resignations came thick and fast on Thursday, with Brexit secretary Dominic Raab, work and pensions secretary Esther McVey and more.
But Mr Raab told the Sunday Times: "If we can not close this deal on reasonable terms we need to be very honest with the country that we will not be bribed and blackmailed or bullied and we will walk away".
