Congratulations with your quit, Orion. Almost three weeks. I quit last November and remember those first weeks very well. Not fun. I was hoping to feel already much better. What I learned here is that you need to put time in it. Physical and emotional improvements are not necessarily noticeable immediately. But looking back you will for sure notice improvements. An immediate improvement is more cash in the wallet! Not smelling awful.
It is so worth it and I do belief the people here that promise us it will go better!!
Keep up, keep busy. Do whatever it takes to keep this quit.
