I could have written your post myself!
The boredom is one of my biggest hurdles in quitting (that and insomnia). This may be a little weird, but what helps me? Eating. I know i might gain a little weight through this... lol But my body feels satisfied after eating something delicious and I don't think about alcohol anymore.
Maybe it'll work for you!
Good luck!!!
Day 3 was SOOO bad for me last time. It was definitely the worst.
