A tired looking David Cameron emerged from 30 hours of talks in Brussels this weekend with a reforms deal for Britain's membership of the EU in hand.
The PM has secured compromises on delays to benefits, child benefit support and an 'emergency break' on implementing EU laws which he said will mean the UK is "stronger, safer and better off" staying in the EU.
The in-out referendum date has finally been set for June 23 - which means all of us, us lucky souls, will now witness about four months of intense campaigning on a once-in-a-generation issue.
While hardly angels themselves, many "leave" campaigners have accused the prime minister and his fellow "remain" advocates of scaremongering.
Some Twitter users have made light of what they call "Project Fear" with the hashtag #BrexitRisks - some of them are especially entertaining - but here are six pieces of straight-up negative campaigning:
1. Russia will love it
Analysts have argued that the Kremlin would be able to lift EU sanctions, and focus on the development of a Russia-led Europe. Its history of human rights abuses, both at home as well as abroad, means this could be detrimental to the EU.
2. The UK will lose money. A lot of money
Earlier this year the Bank of England accidentally sent an email to the Guardian newspaper revealing how stringently it had been researching the risks of leaving the EU.
