Sorry to hear of your lost. I’m a drug & alcohol counselor who works in a Detox facility. Unfortunately a chronic alcohol user becomes physically dependent on the drug. Someone with an AUD no longer drink to feel good but they drink to get well. The body has become dependent on the drug and if they don’t get in their system they will have withdrawals causing their bodies to go into shock. This shock can cause a seizure or even death. Anyone who is battling this disease cannot quit cold turkey without some serious consequences. Your husband truly loved you and y’all kids but unfortunately the disease had taken over his mind. Once the mind is altered with substance abuse it takes a lot of time to get back to a normal state of mind and health. Blessings to you.
