well, i get in this situation quite often. i don't know why but all the german ISPs hate me. personally.
it's like once a year where i don't have internet. sometimes a week, sometimes a full month (happened like 5 times now).
generally i switch into fap-mode and i start getting drunk the minute i arrive at home. i also watch TV then, but the shit in there is so annoying i swith to fap mode and start getting drunk.

Game

suppose watch tv, play my video games and read books.

Nothing really different, just more of the three above since no internet to take time.

Play video games, watch movies and maybe read a bit more.

Try not to drop the soap. Get a tattoo. Lift some weights. Try to stay on the warden's good side.

Mastrubate with the help of magazines..

I think I'll grow more as a person. I'd go to the beach and spend more time reading. Spend more time with family for sure. I neglect them largely because of my internet addiction.

I have a backlog of books I want to read, so I'd work on that.
Don't need internet to play most of my games, so that's still an option.

it depends on what time of the year it is. if it is in Summer rime I would be spending most of my time outside but in winter time I would probably just work more :P

What I usually do when it happens: going more to the sea or skiing or going to country festivals, medieval villages and spas, depending on whether I am at the sea, in the mountains or in the country (it ALWAYS happens when I'm there, I have an Internet connection only in my main residence, in town, and no mobile connection, as I won't pay a dime for fake "flat" contracts).
