An ex-addict was diagnosed with a brain tumour after mistaking her brain fog for caffeine withdrawal.

Abi Feltham, 36, has been sober for four years after dealing with alcohol and drug addiction since she was 14 years old.

She started realising she was drinking a lot of caffeine in November 2023 - having up to 12 cups of coffee a day and reduced her intake.

Abi started having headaches, nausea and brain fog but put it down to caffeine withdrawal.

But when the symptoms started again and she struggled with double vision she went to see her doctor and an optician.

Following a CT scan and MRI Abi was told they had spotted something that could be malignant and she was taken for brain surgery the following day.

Doctors found and drained a cyst which was pushing on a tumour.

Following a second surgery to remove 90 per cent of the tumour, Abi was diagnosed with a grade three oligodendroglioma and told she had roughly 15 years left to live.
