I guess it varies, but sleep is a big deal at first - people can't get any, or get too much etc. It was a big deal for me - I slept like the dead but woke up with splitting headaches, which was weird because I never got any while I was drinking.
Work is good if you can do it - so is plenty of water/tea, vitamin B and taking it easy. If you've been drinking heavily enough to get withdrawals, your body's doing a huge amount right now to try and put itself right. Even if you can't sleep, rest is good.
I've got an old blog under the name Stillsleeping - I haven't read it in forever but I wrote every day in the first couple of weeks. It might help? I don't know haha - it might just be gibberish, but it'd kill the time
