Ups your anxiety level
Alcohol relaxes you in the short term, but makes you more anxious in the long term. This is because alcohol actually depresses GABA over time, partly because it upsets blood sugar balance and rapidly depletes you of nutrients, such as  vitamins and magnesium, which keep you on an even keel.
Disrupts your sleep
You may appear to sleep better under the influence of alcohol but, in truth, it disturbs the normal cycle of 'dream' sleep, known as Stage 1 REM (rapid eye movement). This is when you dream and, without dreams, you can't rebalance from all the day's activities, so you wake up mentally tired and less creative.
Depletes your energy
One of the reasons alcohol is the most popular relaxant is that it reduces tension by depleting your vital energy, much like Letting steam off. Effective it may be, but it leaves you with a much lower level of energy and a hill to climb to get back to a natural high.
It's addictive and an anti-nutrient
Unlike the many natural relaxants in this book, it's addictive. It doesn't take long to acquire the habit. Most people find that drinking just four days in a row sets up a craving. Regardless of quantity, if you 'need' a drink to relax in the evening you are probably mildly addicted. Alcohol, more than any other substance, rapidly depletes your body of almost every essential nutrient, from vitamins to minerals, amino acids to essential fats. It's optimum nutrition's worst friend.
