Amie used to drink 30 pints in a weekend to "keep up with the boys".
"I could neck three bottles of wine and not think about it," said the 38-year-old from Derbyshire.
Her drinking was so extreme that she contemplated suicide: "I thought well, stuff's got to change."
For Jennifer, it caused her relationship with her partner to break down: "I was like a different person when I was drinking - I had blackouts," she said.
A report last year found women are now almost on a par with men when it comes to problematic drinking.
Both Amie and Jennifer had had enough of hangovers - and decided to give up alcohol.
