There were a couple of years i was starting to go into withdrawal around 5pm. At the time i did not know that was what it was because I would be getting a drink into myself as fast as possible. It just reached a point where there was no denying that withdraw was what it was. That realization hit me like a ton of bricks(but still did nothing about it.
When I finally quit from 5pm till I slept was ever increasing anxiety.
