Grace Parkin can remember the exact moment when a pint of beer began to taste a bit…off.
It was the summer of 2024 and the then 32-year-old manager was watching the European football championship with a group of friends at a favourite pub.
Ordinarily she'd polish off several pints of larger in one evening – but this night was different.
'I ordered a beer out of instinct,' said Ms Parkin, who hails from Sheffield.
'But I couldn't even get a third of the way down. I tried to drink it all but I remember thinking, "oh god, this is not for me".
'It didn't have the same effect it used to. It didn't taste nice at all and made me feel bloated.'
It would transpire that the mother-of-one was experiencing a bizarre – but increasingly reported – side effect of the popular weight loss injection, Mounjaro.
Ms Parkin, who lost six stone after 18 months on the jabs, is also less drawn to wine, as well as her spirit and mixer of choice, too.
Grace Parkin, 34, found that Mounjaro had a positive effect on all of her impulsive behaviours
Prior to starting the so-called 'blockbuster' injections in May 2024, Ms Parkin would sometimes get through 'up to 10 vodka, lime and lemonades' on her weekly Saturday nights out.
These days, she's switched to wine – but only on occasion.
'Sometimes I have to force myself [to finish a glass of wine],' she said. 'I’d probably say I’m drinking once a month as oppose to once a week. I’m not interested in it whatsoever.'
A growing body of research suggests that the medications, called GLP1-agonists, have an additional benefit of curbing cravings for a number of substances.
Studies show that using the drug can cut the risk of developing alcoholism by 18 per cent, and cocaine addiction by 20 per cent.
