Blood sugar, wine, and why evenings feel harder
If evenings feel harder without wine, there is often a blood sugar story underneath.
Alcohol can temporarily lower blood sugar, which creates a brief sense of relaxation. But this is usually followed by a rebound rise later in the night. Over time, the body learns to associate evening relief with alcohol, not because of habit or weakness, but because of biology.
When alcohol is removed, low or unstable blood sugar can show up more clearly. Irritability, cravings, restlessness, feeling wired yet flat, or emotionally low in the evenings are all common signs.
This is not a lack of willpower.
It is physiology.
A few key factors make evenings more vulnerable. Insulin sensitivity is naturally lower at night, meaning the body does not handle glucose as efficiently. Melatonin, the hormone that rises to prepare us for sleep, also reduces insulin activity. Eating late, especially refined carbohydrates, can therefore push blood sugar higher and then lower again overnight.
This is why eating earlier matters. Having dinner earlier in the evening gives your body more time to process glucose, leading to steadier blood sugar overnight and often better sleep.
What you eat matters too. A dinner built around protein, healthy fats, and plenty of non starchy vegetables helps compensate for lower insulin sensitivity in the evening and reduces the urge to reach for something sweet or soothing later on.
But this does not start at dinner. Your first meal of the day sets the tone. A balanced breakfast, particularly when eaten earlier in the morning, supports insulin sensitivity for the entire day. Skipping breakfast can actually lead to higher blood sugar responses at lunch and dinner, making evenings feel much harder.
This is one of the reasons nourishment matters far more than restriction during this month. Supporting blood sugar consistently through the day often makes the removal of alcohol feel gentler and more sustainable.
If evenings are your hardest time, save this post and follow along for practical, hormone supportive guidance this month.
