First 3 days for me I was alone, did loads and loads of reading on SR (all inspirational stuff both good and bad and realising your are not ALONE helps), watched TV, downloaded movies etc. Taking it all an hour at a time, small pieces that I could manage. Everybody finds their own way to manage......if its drinking pepsi (so be it), if its just lying on the couch watching serials / movies (so be it), if its going to the gym (so be it), if its cleaning out the garage it does not matter what gets you through so long as you stay away from alcohol.
So keep going, dig deep. Everyday hour you don't drink is a step in the right direction.
