Hey Adam - damn glad to meet you. And congrats on making the decision to quit.
You've probably already done your reading, but these next are going to suck. They're going to suck the life out of you, they're going to make you so irritable that every little thing will piss you off, and they only thing you'll think about is dip. I'm on Day 6, and even though I'm getting past some of that shit (I feel pretty similar to having the flu), but it's worth it. You're going to look back on this first awful week in a few months and be so glad you did it. Everyone's been through this, so reach out to anyone if you have any questions or anything at all.
