Penny Whitaker, a 45-year-old mother of three from Suffolk, started taking Mounjaro in July 2025 and lost two stone, returning to a size 10 figure. According to Daily Mail - Health, she described increased emotional sensitivity and arguments after drinking alcohol while on the medication. She noted that before, a glass of wine would help her relax, but now it seems to do the opposite, making her feel low, anxious, and far more sensitive than usual. Other weight-loss jab users have reported dramatically reduced alcohol tolerance, with even small amounts causing stronger effects.
A 42-year-old mother who lost three stone on Mounjaro said the weight loss led to increased confidence but also the breakdown of her marriage and an affair. According to Daily Mirror - Main, she described how her husband admitted he preferred her before weight loss and missed her curves, showing jealousy over compliments from other men. She has been having an affair for two months with a man who appreciates her new look. She said she thought losing weight would improve everything but did not expect it to threaten her marriage.
I felt that something was wrong with me. Why can't I solve this?
Gogglebox star Amy Tapper lost 8 stone using Mounjaro and stated she will need lifelong weekly injections. According to Daily Mirror - 3am Showbiz, she described Mounjaro as not a quick fix, noting that her eating and exercise habits were already good before the medication. She described her mind as more 'peaceful' and free from food-related thoughts due to the medication.
Louise Nyström from Borås Tidning used weight loss injections like Mounjaro and Wegovy after years of binge eating and fluctuating weight. According to Borås Tidning, she described feeling that something was wrong with her for not being able to lose weight on her own.
The medical mechanisms behind Mounjaro's effects on alcohol tolerance and mood remain unclear, and the prevalence of relationship issues among users is not well-documented. No clinical studies or official data on these specific side effects have been released, and it is unknown what support or counseling is available for users experiencing relationship difficulties.
