Self care/activity tips in early sobriety?

Here we go again! My fourth attempt at at home detox. I went to the emergency 3 days ago due to unbearable withdrawals. I was on the waitlist for in hospital detox but couldn’t take it anymore. I was given 20, 5mg of Valium. What did you do in the early days to keep yourself occupied? So far I’ve been cleaning and organizing obsessively, chain smoking as well, to keep myself busy - but in the past me working so hard has led to me binge drinking as a reward. But for me this is the last time as I can’t continue on like I had been before. Also open to any nutrition suggestions as my stomach is pretty messed up.
