The UK’s alcohol guideline recommends no more than 14 units per week for both men and women. Yet many women unintentionally exceed this — particularly through wine.
This is rarely deliberate. It is usually mathematical.
How Wine Units Add Up
A medium (175ml) glass of 13% wine contains around 2.3 units.
A large (250ml) glass can contain 3 units or more.
Two large glasses on three evenings per week equals 18 units. Add a social occasion or weekend drinks, and weekly intake can easily reach 25–35 units.
What feels moderate can quietly exceed recommended levels.
Midlife, Hormones and Alcohol Tolerance
Many women in their 40s and 50s report:
- Reduced alcohol tolerance
- Poorer sleep after drinking
- Increased anxiety (“hangxiety”)
- Weight gain
Hormonal changes can alter alcohol metabolism and sensitivity. The same quantity consumed in your 30s may feel very different in your 50s.
This often triggers the desire to reduce drinking — not necessarily stop, but regain balance.
Habitual vs Dependent Drinking
Many women describe their pattern as habitual:
- A glass while cooking
- A glass while watching television
- A drink to unwind
It becomes routine rather than a conscious decision.
Reducing alcohol intake in this context is about behaviour and reinforcement, not necessarily addiction.
The Neurological Reward Pathway
Alcohol stimulates the release of endorphins and dopamine, reinforcing repetition. Over time, this strengthens the link between drinking and relaxation.
For some women, tracking alcohol units is enough to prompt change. For others, the urge to continue drinking after starting remains difficult.
Naltrexone is a clinically researched medication used in alcohol reduction. It works by blocking opioid receptors involved in alcohol reward, reducing reinforcement over time.
It supports moderation rather than requiring abstinence when used under clinician guidance.
Reducing Drinking Without Extremes
Alcohol reduction does not need to be all-or-nothing. Practical steps include:
- Measuring wine accurately
- Setting alcohol-free days
- Tracking weekly units
- Identifying emotional triggers
Awareness plus strategy increases success.
Understanding alcohol units is empowering. Support makes it sustainable.
