This is great! So glad you're here with us! I'm on day 26 (I think) and I NEVER EVER thought I'd make it this far without drinking, especially since I was an everyday drinker. Proud of you.... before long you'll be at a month and then a year.
My emotions were similar during my first week. I'd have moments where I'd be ecstatic and happy about the life change, and then I'd get random moments of extreme irritability and anger. I think a lot of the negative emotions popped up because I'd been drinking away my problems for so long that when I became sober, all my problems became VERY REAL and I actually had to deal with them. Also, mentally/emotionally I wasn't used to not having that crutch to come home to every night to put me in a different reality, so I was kind of a ***** those first days.. which I felt was reasonable...
I can definitely say however that the crazy up and down emotions have leveled out at this point and aren't near as bad in the first few days.
Keep on keepin on!
