Hey there,
I'm at 140 days and can relate a little bit to what your going through...pure boredom.
I started doing things by myself that I couldn't do while sitting at home staring at the computer...drinking.
This is my go to list of alone activities:
Take a night drive....couldn't do that before (too drunk)
Go to the library....and find some good books (reading takes me to a new place)
Reorganize something....after years of drinking, everything needs to be tidied up.
Go to a movie or out to dinner alone......no pressure to drink (I avoid all drinking establishments, even restaurants that have large drinking areas)
Take some college classes online....I'm finishing up a degree online, keeps my mind busy!
Just some ideas....boredom while sober, is better than boredom while drunk. And being drunk is so boring!!!
