Hi RLH
I think most of us can remember feeling exactly as you do.
It took a great adjustment for me to put my recovery first - but I knew it needed to be done. I'd tried the 'kinda sorta committment' many times - simply living my old drinking life but trying not to drink - I failed miserably every time.
Give yourself time - this is your first week. You will make changes in your life that better reflect sober you and you will develop 'sobriety muscles'...one day - not too far off - you'll find you can go anywhere and do anything because you've worked at it, you've changed a little and you know you want to be sober and prefer it that way.
I've never regretted getting sober - I'm sure you won't either.
Even when I felt it was unfair and stupid and I wanted to throw a toddler tantrum and run after my mates and just forget about recovery, I knew my addiction was driving that response...and I didn't want to be that guy anymore
Hang tough
