It’s good to see you on your sober journey again 
have some tools ready just in case the urge bites, and read lots here. I love the What’s YOUR plan? post for support in the early days and beyond.
My goodness.. when you mentioned that sickly feeling the day after drinking I FELT IT. It’s such a horrible memory 
It’s like a mental scar, and I pray it never leaves me. Use your memory of that morning to your advantage x
