What's really happening
As your hormones shift during perimenopause and menopause, your body changes the way it processes alcohol. You may feel tipsy faster, have worse hangovers, or experience hot flashes, headaches, and heart racing after just one drink.
But why?
Lower estrogen, decreased liver efficiency, and less body water all contribute to heightened alcohol effects.
Scientific Breakdown
As you age, your liver becomes less efficient at metabolizing both alcohol and hormones. This means alcohol lingers longer, interferes with hormone clearance, and can increase symptoms like night sweats, mood swings, and poor sleep. Decreased water retention and alcohol-processing enzymes in women intensify its effects, often leading to stronger intoxication and hangovers.
Estrogen & progesterone fluctuate → increased sensitivity
Liver function slows → alcohol stays in system longer
Less body water → alcohol is more concentrated
Essentially…
Your body simply doesn’t process alcohol like it used to. The enzymes that break down alcohol are lower. Your liver is multitasking more than ever. And estrogen dips make you more vulnerable to the effects. That fun glass of wine now acts like a double shot of espresso—plus a diuretic and a sleep disruptor.

Alcohol symptoms are severe, sudden, or interfere with sleep, digestion, mood, or heart health.
Intense reactions could signal histamine intolerance, medication interactions, or liver issues.
Frequently Asked Questions (FAQs) about
Alcohol Intolerance
• Why can’t I drink like I used to?
• Does wine really trigger hot flashes?
• Are mocktails better?

“I thought I had to give up wine forever. But once I got my hormones balanced, I could actually enjoy a glass again without the night sweats or anxiety spiral. Total game-changer.”

FLUXX Recommendations
1. Track your reactions to alcohol by type and timing
2. Choose lower-histamine drinks or non-alcoholic alternatives
3. Prioritize sleep, hydration, and mood support on drinking days
Non-Hormonal Medications
N/A, though antihistamines may help for some with histamine-related responses
• Swap wine for clear spirits or mocktails
• Add herbs that support the liver (e.g., dandelion, milk thistle)
• Use quercetin or vitamin C to lower histamine response
Lifestyle Suggestions
Dr. Flagg's Alcohol Strategy
While ZERO alcohol is by far the best for health span, that's no fun. Alcohol, after all, is a common part of the fabric of our culture.
#1 Anything you do daily is a habit. There are good habits and bad habits. Daily alcohol is a bad habit. Have some alcohol free days.
#2 When you drink, have 1 or maybe two, not 3 drinks. Start with a glass of water, sip on 1/2 a drink, have another glass of water then drink the other 1/2.
#3 We all know this saying! "Do not drink alone!" When you drink- socialize + interact. Keep that brain engaged in meaningful ways. We have scientific data showing very clear benefits of socializing and engaging.
A couple more more tips:
Drink earlier in the evening, not before bed
Eat before and during drinking
Myth-Busting
Wine might feel relaxing at first—but it often disrupts sleep, worsens hot flashes, and raises health risks. During menopause, wine may be the reason you’re wide awake at 3am.
Modern Guidance
Most experts now recommend no more than one drink per day for women, and even less during menopause. Pay attention to how alcohol affects your sleep, mood, and symptoms. Cutting back—even a little—can make a noticeable difference.
Ask yourself
• Do you feel flushed, hot, or anxious after drinking?
• Does alcohol disrupt your sleep?
• Have your hangovers gotten worse lately?
Ask your doctor
• Could these reactions be hormonal?
• Would a liver function test help?
• Should I consider stopping alcohol altogether?

Alcohol may increase hot flashes, worsen sleep, and interfere with hormone balance. It can also raise your risk of breast cancer, especially with regular use.
