Thanks for all of the well wishes
Thanks all. I fully expected withdrawal issues after 18 years. I literally don't remember my last sober night before this stretch. Feel awesome again today despite that I've only been getting about 6 hours of sleep per night, even when I had the extreme fatigue. Feels so weird trying to go to bed sober, but I think the 6 hours of good sleep beats the 8+ hours of drunk sleep hands down.
I worry about my first sober weekend feeling good and energized, so I arranged to attend my first AA meeting Saturday night, when I typically hit the bottle the hardest.
Again, thanks for all of the support.
