Hi - welcome to SR :-)
Your making a great decision to quit and doing amazing already! - its great here and you will find loads of support
Why not get your husband on board as well?,.its tough enough as it is and strength in numbers will really help!
I would be little concerned if everything your addicted to is still around you,you need to shake him up as well- you sound really strong so give him a nudge!
First few days withdrawal are always dreadfull - gets better I promise! :-)
