Indeed, life is so much better sober, but, I feel like not enough people talk about things like PAWS- post acute withdrawal syndrome, and I know for me it definitely helped knock my ass off the wagon!
PAWS doesn't happen to everyone, but basically, you do start to feel much better and improve your life, then around 4-5 weeks in, you start to feel worse: tired, irritable, and the one that hit me the most, bouts of insomnia and nightmares. I simply could not sleep more than a few hours for over a week, and when I did sleep it was full of really fucked up nightmares. I was tired, beaten down, and really pissed at the world, lol.
But, eventually it did pass after about 10 days, and after that it's been really smooth sailing. Looking back on my previous attempts at sobriety, PAWS totally hit me when I hadn't heard of it, and it definitely was a MAJOR factor in my previous relapses.
The other big thing is being patient- but persistent- with yourself. Many times I would think, "why the fuck don't I feel BETTER yet? It's been _____ amount of time, why do you I still feel tired, weak, etc?". Then I realized, hey, I spent so many YEARS destroying my braincells, body, and biochemistry, it's gonna take just a little of time for those things to heal, and then more time on top of that for them to strengthen themselves again! The more poison that you've pumped into your body over a long period of time, the longer it's gonna take to feel better!
So yeah, life DOES get so much better in every way possible, but, you gotta arm yourself with the knowledge and skills to deal with PAWS, as well as the inevitable challenges, temptations, and frustrations that you WILL eventually be forced to battle.
Tackle it just like Jiu Jitsu/Muay Thai/Boxing: you WILL face a ton of adversity that makes a lot of people give up, but, if you commit to yourself and push through, you enter a world beyond compare. And, just like in Martial Arts, LEARN and GROW from every single experience you have, especially the "defeats" or bad times.
Stay strong, be patient, but always persistent; and commit to freeing yourself.
