The 47-year-old, who has a long history of problems with alcohol, was found slumped outside his home on Thursday August 21.
Looking pale and unhealthy, the ex-England player, known as Gazza, carried a bottle of gin and a pack of beer when he was taken into hospital, escorted by police officers.
But yesterday he appeared composed and looked more healthy when he arrived home and gave a thumbs-up sign to waiting reporters and photographers.
Twitter users sent messages of sympathy and support to his daughter, Bianca, a model and reality TV star.
The former star has recently signed for Bournemouth Sunday League team Abbey.
Gazza is said to have blown his £14 million fortune on drugs, alcohol and failed business ventures.
Five years ago he was said to be down to his last £250,000 and narrowly avoided being declared bankrupt.
He currently rents a luxury flat but the management company at the block has said his lease will not be renewed when its runs out next month.
The popular footballer becamse an overnight millionaire when he was transferred from Newcastle to Spurs in 1998.
In 1992 his earnings increased when he landed a £1.25 million a year contract with italian club Lazio and also won several lucrative sponsorship deals.
On his return from Italy, he continued to earn at least £1 million a year with Rangers.
