British singer Amy Winehouse’s agonizing life continues just as agonizingly, as she was admitted to a London clinic over the weekend after she suffered a reaction to medication.

Chris Goodman, a spokesperson for Amy Winehouse revealed the singer entered the London Clinic on Sunday to receive treatment for a reaction she had to medication. Goodman would not detail the meds troubling Winehouse. She is being kept there for tests.

The 25-year-old singer has been hospitalized before for similar problems. In July, she was at her home when she felt ill. Luckily for her, her father was also present and quickly acted.

Amy Winehouse’s health has suffered greatly due to her history of drug problems. It was only a year ago, around the time she married Blake Fielder-Civil in May, that she mischievously told reporters she was a “nasty drunk” and that she shied from nothing when she wanted to prove her point.

What appeared to be rebelliousness and a rocker chick persona soon turned into a real problem, both for her and her young husband, as they shifted from one rehabilitation center to another, never staying long enough to benefit from the treatment.

In August 2007, she was hospitalized after ingesting a mess of a cocktail with ingredients such as cocaine, heroin, ecstasy, ketamine and crystal meth. At the time, she initially said she had been hospitalized for exhaustion.

A couple of months ago, British paper The Sun ran an article quoting a concerned friend of the singer’s who revealed the above-mentioned incident had been Winehouse’s first overdose. Her second overdose, the same friend says, occurred in July of this year, when she allegedly inhaled an “inhuman” amount of marijuana.

Fielder-Civil was released last month on parole after serving nearly a year behind bars for assault and obstructing justice. He was conditioned to enter a rehab center.
