A primary school teacher who rarely drank alcohol died after drinking more than one bottle of red wine on a summer afternoon.
Gill Howe, 46, may have lost her life because her body had a very low tolerance of alcohol, an inquest in Hull heard.
The mother-of-two, described by her family and friends as "full of life, always laughing and happy," had been in her garden with a friend in June last year when she became unconscious.
Paramedics struggled to resuscitate her and she "slumped forward" in her chair, having drunk one and a half bottles of wine.
The popular teacher died whilst traveling from her home in Beverley to Hull Royal Infirmary.
