To me, it seems like the hangover isn't the problem. It's that you are only 27 is the problem. I remember when it came to my wedding day at 29, I realized that was my first "controlled" drink. I didn't realize it back then. I went on and drank for another 10 years until I got into high-risk activities, my marriage suffered, didn't communicate well with children, missed work deadlines, etc. And now I'm living on border-line to lose everything. It will only take one big mistake to lose my license and derail my long, excellent career. Now, it's VERY hard to quit drinking but I believe it can be done as I'm ready to move to step 2. I wished I stopped drinking when I was 27 and stop for good.
