The Scottish Conservative leader was responding to an article by Nicola Sturgeon in the Sunday Herald in which she sought to dismiss the significance of oil, Scotland's national wealth and its deficit.
All these issues formed a major part of the SNP's discredited white paper on independence in 2014, when the party tried to claim separation would deliver a financial benefit to Scotland.
However, amid fresh evidence of the impact of the falling oil price on Scotland's wealth, Sturgeon today used an article marking the second anniversary of the referendum to downplay the significance of these key issues.
It comes as another poll, in the Sunday Times, revealed that there is dwindling support for a second referendum on independence - only 33 per cent of people want another vote in the next two years
Scottish Conservative leader Ruth Davidson said:
“The economic case for independence two years ago was a tissue of lies.
"Fantasy figures on oil and our national wealth concocted to fool people and which fell apart under scrutiny.
"Now everyone can see Nicola Sturgeon's sums don't add up, she's decided to abandon them altogether.
"Instead of trying to explain what would happen to our economy and how we fund our public services under independence, the new mantra is that none of these things matter anymore and people should just shut up about them and wrap themselves in a flag instead.
"I think Scots are smart enough to draw their own conclusions.
“The country examined the case for independence two years ago and said No thanks.
"Scotland will suffer if we keep being dragged back by the SNP to a ground-hog day debate about this.
"It’s time Nicola Sturgeon did what she's paid to do - be a First Minister for all of Scotland, not simply a rabble-rouser for independence.”
On today's poll, she added:
“Two years on from the referendum, support for a second referendum is nosediving.
"The message to Nicola Sturgeon could not be clearer: Scotland doesn't want to go back to the divisions of the past.
"People want a Scottish Government focussed on the day job. It is time for the SNP to listen, so we can all get on with our lives.”
