A spokesman for the singer said her hospitalisation on Sunday was due to a "bad reaction to the combination of medication she has currently been prescribed".
However, a friend told The Sun that the 25-year-old went on a 24-hour binge after a blazing telephone argument with her husband Blake Fielder-Civil.
The source said: "They had a screaming row. She was beside herself after the call - and she just totally lost it. It didn't stop until she was on the floor on Sunday.
"She has ended up in hospital a few times after similar drink and drugs related seizures. If she carries on, one of these incidents will be her last."
While the Back To Black singer recovered in hospital, Fielder-Civil failed in a legal bid to have his 27-month jail sentence reduced for assault and attempting to pervert the course of justice. He is currently receiving rehab in Surrey as part of the terms of his early release.
Winehouse was diagnosed with the early stages of emphysema in June and spent a short spell in hospital last month due to a suspected chest infection.
