Day 4 was always my relapse day! The story I told myself and believed that this was because Day 4 was the hardest part of detox and therefore I failed because of that. So back to drinking for a while. Then repeat the whole thing again.
This went on for long time. Eventually I got passed Day 4 seemingly by accident and have been quit ever since. Approaching 8 years now.
I later came to discover that the whole cycle of relapsing on Day 4 was set up by me. My get out clause to go back to drinking!
