A pastor has discovered that his gut has been brewing its own alcohol every time he eats carbs due to a rare condition.
Although, at first glance, it might sound like a brilliant problem to have - that hasn't been the case.
Adam Stump suffers from auto-brewery syndrome (ABS) and it would lead him to becoming very drunk and aggressive, without touching a drop of the hard stuff.
The 40-year-old would often black out and slur his speech.
His bewildered wife Jana Stump, 37, was convinced that her hubby was an alcoholic.
It was only when the stay-at-home-mum realised something was wrong when breathalysers showed Adam was over the legal driving limit, despite spending the entire day together without drinking.
After various trips to the doctors, who also thought he was a secret alcoholic, it was discovered that he had been suffering from ABS.
The dad-of-four now takes antibiotics to manage his condition.
Adam, from Pittsburgh, Pennsylvania, USA, said: "At the start, Jana didn't believe I hadn't been drinking. She thought I was sneaking it somewhere. I had to convince her that I hadn't been drinking.
"It was terrible for her to think that I was living a double life. When I was diagnosed, she collapsed and said she couldn't take any more stress.
"I would slur my speech, black out and walk around talking but not remember any of it. I was quite belligerent and combative. I didn't hurt anyone but once I threw the dining room table and had to get a friend round to calm me down.
"There were a few times where my wife would be looking for me and I'd be in strange places like the garden or laying on the basement floor with no recollection of how I got there."
He added: "I wasn't a very pleasant person to be around. I felt like I was going to snap.
"Some people can be funny when they're drunk but that isn't what auto-brewery syndrome is. It's a personality changer. It's like having a hangover and being drunk at the same time."
After discovering Adam wasn't secretly necking booze, Jana suspected he may have auto-brewery syndrome after researching the symptoms.
After undergoing testing, doctors revealed Adam had ABS in February 2021 and began treatment in March.
Now Adam has been forced to give up practically all carbs and lives on a diet of meat, cheese and eggs.
The difficult withdrawal symptoms - including nausea, diarrhoea and stomach cramps - meant Adam was forced to take three months off work.
He concluded: "I've got to the point where I've realised it's better to be healthy so it doesn't bother me to see people eating and drinking. It's worth it to be a husband and father."
