King I have had so many first in my first year sober and I can honestly say I do not miss drinking at all, especially on Holidays, I actually remember all of them and actually participate in them. My first Christmas sober was great, it was the first time in years I set up the tree and decorated it. Oh yea I was amazed how much better the trees lights looked hung by a sober person (me) compared to how they looked on the rare occasions I did them drunk.
In regards to hangovers the only time I had them was with wine and if I mixed hard liquor & beer, the only thing I ever had the morning after was one of 2 things, I was in a fog or still half lit.
