Some of the best points I've heard about drinking and why to quit:

• If you do drink: Take vitamins, electrolytes, and probiotic supplements to help protect your body. Cold showers help recovery too.
• Non-Alcoholic beers, wines and even spirits, have gotten pretty impressive in variety and taste these days. Keep some on hand or take them to a party, to resist drinking alcohol instead.
• Use a drink counting app on your phone, to know exactly how many drinks you have had that night, and to mark off which days you abstained.
• Avoid day drinking or "hair of the dog". The more hours of the day with alcohol in the system, strengthens withdrawal and addiction.
• Sleep while drinking, is fake sleep. Not enough REM and deep sleep. If you're having trouble sleeping, try a supplement like melatonin before bed.
• One night of drinking will affect the brain's ability to decide whether drink or abstain for up to 2 weeks after. One reason why quitting can be difficult.
• Any relationship with alcohol, is like an abusive relationship. There are fun times and bad times, but eventually, the abuser will always hurt you. You can’t change the abuser, and you can justify as much as you want, but the only way to stop getting hurt is to leave the relationship.
• Alcohol interferes with your body's natural cancer fighting abilities. The strength of the alcohol and cancer relationship, appears to be well suppressed by the MSM.
