Most of us drink alcohol to socialise or relax.

But for some people, drink becomes everything.

Dr. Julia Lewis sat down with ITV News to explain the complexity of addiction.

Dr. Julia Lewis is a Consultant Addiction Psychiatrist and clinical lead for a specialist addiction service in the Aneurin Bevan University Health Board.

She is also Clinical Director for Adult and Specialist Mental Health Services in ABUHB.
