A young mother choked to death on her vomit after eating a Kinder Beuno while drowsy on painkillers , an inquest has heard . Candice Campbell , 25 , who had taken the medicine to help her post-natal stomach pain , drifted off to sleep while eating the chocolate bar . Miss Campbell , mother to one-year-old son Harrison , then choked as she was sleeping beside her fiancé on the couple 's sofa in Hull . Doting : Mother-of-one Candice Campbell , 25 ( pictured left and right with partner Geoffrey Burns ) , choked to death on her own vomit after eating a Kinder Bueno before falling asleep on the sofa , an inquest has heard . Her husband-to-be Geoffrey Burns , who had also fallen asleep , woke up to find his partner 's lifeless body slumped onto his knee . Despite him desperately giving CPR to Miss Campbell , she could not be saved . Miss Campbell , who did not drink alcohol , had been taking a variety of prescribed medication to ease abdominal pain which she had suffered after giving birth in October 2013 . At an inquest into her death , Mr Burns told the hearing how he had warned Miss Campbell not to eat the bar , incase she fell asleep . He told how the pair had both fallen asleep while watching a film , but that he had woken up around 5.30am to find Miss Campbell unresponsive . He said : 'Candice was eating a stick of Kinder Bueno and I told her not to eat chocolate in case she fell asleep because her medication makes her drowsy . I was worried that she may fall asleep eating it . ' I must have been tired because I fell asleep . I woke up to the dogs barking and Candice 's head was on my lap . The first thing I remember saying to her was , `` Wake up , let 's go upstairs '' . ' I noticed her lips were blue and there was a white foam coming from her nose and food particles at her mouth . ' Mr Burns said when he realised she was not responsive , he began CPR . An inquest heard how Miss Campbell was watching a film with her partner at their home in Hull when the pair both drifted off to sleep . Mr Burns told the inquest that he had warned her not to eat the bar ( pictured ) He said : ' I gave her mouth to mouth and pressed down on her chest as I was taught at first aid . ' I continued to scoop out food from her mouth and I saw there was the Kinder Bueno she was eating before I fell asleep . ' I tried to resuscitate her . I blew twice into her mouth and did 32 compressions . ' The inquest heard how Mr Burns then ran 12 doors down the street to Miss Campbell 's parents ' house to get help . Her father , Ian Gibson , also attempted CPR before they called for an ambulance . Dr Ian Scott , consultant neuropathologist at the Queens Medical Centre in Nottingham , carried out the post-mortem examination . He said toxicology tests revealed Miss Campbell had taken several different drugs , including diazepam , tramadol , pregabalin and 'possibly ' dihydrocodeine . He said that although Miss Campbell had not taken a 'fatal ' amount of each drug , the combination had been enough to depress the central nervous system , which left her unable to clear her airways if she vomited . Dr Scott said : ' I found debris impacted in the trachea and material similar to that which is found in the stomach . 'Where a patient may vomit and then inhale what 's been in the stomach it causes asphyxia . The cause of death is asphyxiation due to aspiration of gastric contents . There is no suggestion that this was a deliberate overdose . ' During the hearing , Mr Gibson paid tribute to his daughter . He told the court : 'She was a good mum and would have done anything for Harrison . She doted on him . 'She loved being around people , she had a lot of friends , She was also a real family girl who enjoyed spending time with them . ' Senior coroner Professor Paul Marks recorded a verdict of accidental death , calling it a 'tragic case ' . He said : 'This is a very tragic case where a young mother had been enjoying an evening with her partner and fell asleep . 'She vomited but was unable to clear her airways . There is not a shred of evidence to suggest Candice took more medication than she should have . '
