Welcome and congrats on this milestone! I totally understand what you describe in self discovery. Letting go of what I had been considering fun., and even lifelong ideas like how (only) extroverted I am was a process and sometimes (on that latter part since the "fun" of drinking quickly became obvious as totally wrong!) strange journey.
In two and a half years and change, I have kept discovering and importantly, being able to choose who I am and what I want to do- also learning to accept my flaws along with my preferences.
Keep going. Life is so much better sober as you already see, and it keeps growing.
