Former Labour strategist Alastair Campbell, who was a long-term friend of Charles Kennedy, told the BBC News Channel that he never felt Mr Kennedy was "truly on top" of his alcohol problem.
Mr Campbell said: "He did take a long time to confront it. I think that because I'd had my own problems with alcohol I think I may have been one of the first people that he came to.
"I can remember we went for a walk in his constituency and he said 'look, you know what, I think I do have a problem'... I do think if Charles had maybe confronted it earlier he might have ended up with a happier existence."
The Liberal Democrats have invited members of the public to submit messages for inclusion in a book of condolence, that will be passed on to Mr Kennedy's family.

The former leader of the Liberal Democrats Lord Steel told Newsdrive that Mr Kennedy was a principled politician and a valued friend.
He said: "He was a great character. He had a wonderful sense of humour as well as strong convictions, so he was a delight to have supper or dinner with on occasion."
Lord Steel continued: "I think he would have played a major part in the upcoming referendum on Europe. He was president of the European movement and he felt very strongly on that issue, so he would have been on natural territory all over the country , had he lived.
"I think we will miss him greatly in that campaign."

Anecdotes and wry observations spilled from Charles Kennedy. He had an acute intelligence and a thoroughgoing comprehension of contemporary politics.

Read my blog in full. for my thoughts and memories of Charles Kennedy.
Born in Inverness he grew up on the family croft at Lochyside in Lochaber in the shadow of Ben Nevis, with his late and extremely musical parents Ian and Mary.
He attended Lochyside Roman Catholic Primary School just a stone's throw away from his home, and later Lochaber High School, where he honed his debating skills.
Fellow pupil and journalist Hugh Dan MacLennan told of how Charles used to practice oration during lunchtime, while the other boys played football and shinty.
After being awarded an honours degree at Glasgow University, Charles Kennedy was offered a Fulbright Scholarship to the United States.
He returned from America the states agreeing to fight the seemingly 'no hope' seat Ross, Cromarty and Skye for the SDP in 1983.
He won and Britain's youngest MP at the time went on attribute his continued success in the seat to his strong Highland roots.
Nick Clegg: "Charles Kennedy was one of the most gifted politicians of a generation, he always spoke with great humour, humility and courage."
Paddy Ashdown: "He had his difficulties, he had his demons...but on form and on song, he was the best of us by a mile."
Alastair Campbell: "A lovely man, a talented politician, and a great friend."
John Bercow: "Charles had that rare and uncanny capacity to cut through to large numbers of voters of all political persuasions and of none right across the country."
David Cameron: "He was a talented politician who has died too young. My thoughts are with his family."
Tony Blair: "He was throughout his time [in parliament] a lovely, genuine and deeply committed public servant."
Gordon Brown: "I recognised his ability and asked him to join the Labour Party. He politely declined."
Lord Rennard: "CK' as he was often known, was one of remarkably few people in politics who would find appropriate, but sometimes unusual words, to understand and express peoples' emotions. Many of us will struggle to do that now."
Image source, PADanny Alexander: "We will miss him more than words can say."
Willie Rennie: "...that cheeky smile, that Highland voice, and just a few well chosen words: He was able to catch my political heart and many people right across the nation."
Nicola Sturgeon: "A lovely man and one of the most talented politicians of his time. Gone too soon."
Alex Salmond: "When it came to a decision when the establishment was facing one way and the people were facing the other way, he took the side of the people."
Jim Murphy: "In years to come we will remember with a smile the delight in knowing him, his huge contribution to politics and a life lost too soon."
Lord McConnell: "Talented, principled and extremely likeable over the 35 years since we first met. Very sad."
Henry McLeish: "He was an easy man to like and above all else a real patriot, and always concerned with social justice."
Nigel Farage: "I am very sorry to hear the news about Charles Kennedy, he was always a polite and decent man."

Former Deputy First Minister Lord Wallace has spoken of his "profoundly personal" memories of Charles Kennedy.
He said: "What I will probably remember most were his instinctive humanity, his infectious good humour and his determined, even stubborn commitment to the principles and the values he believed in.
"Much will be written and said about the key moments of his career; but my feelings today are profoundly personal.
"It's about the loss his family are experiencing, and not least Donald [his son], of whom Charles was intensely proud. It's about the loss to our public life, as he still had much to contribute. It's about the loss of a friend.
"But even in sadness, memories can't help but bring a smile. It'll be a long time before we see his like again."
Image source, PACampbell on Kennedy: "Relations between himself and myself were a bit cool to begin with" but later "we restored the warm and friendly relationship which we had had".

I doubt if Charles Kennedy was surprised he lost his seat. I think the truth is it was quite clear to anybody who had looked at the opinion polls that he was in trouble.
Image source, Rex FeaturesCharlie Kennedy, throughout his career, people remember him as a very social person. He is also somebody that during his career he was willing to take risks and to stand on his own. It very clearly marked the leadership of his party.
Two things - arguing for more taxation for spending on education and opposition to the Iraq war - in 2005 attracted a section of the electorate that was unhappy with new Labour, and that lead to the fact the party got to 62 seats in the general election.
Charlie Kennedy went against the tide, took risks, and his party profited from them.
Alex Salmond has said he does not think Charles Kennedy was fully behind the Better Together campaign during the Scottish independence referendum.
Image source, Matt CardyThe former Scottish first minister told the BBC: "In terms of the independence campaign, I don't think his heart was in the Better Together campaign.
"His heart would have been in a pro-European campaign - that's the campaign that Charles would have engaged in heart and soul."
