I was a weekend binger, every few weeks. I'd obsess over it for a few days, not be able to sleep the night before because I was looking forward to it so much. The first evening would be a civilised meals with friends and then a late night bar until around 2am. Sometimes I wouldn't even blackout.
Then the 2nd day I'd wake up around 9-11am ish and start straight away. Completely a mess by late afternoon.
3rd day I'd start early again to clear the shakes and if I was visiting friends in order to make the train or car journey home bearable.
After that I'd feel miserable for at least a week, but the shame would make me work harder in the gym and eat really healthily. After a week or two I'd start obsessing over drinking again.
Sometimes the bender would last up to 6 days, these would take me to a very dark place. I'd cross roads in front of cars willing them to hit me. I just didn't care.
