I've said this before...I am 43--and I so wish I would've quite drinking in my twenties. I have always been "high functioning" (what a joke) One thing I HAVE done right is I have kept a journal for twenty years--when I was around 24 yrs, I started questioning how much I drank. I was researching it at the library! I continued for many more years.....and it only got worse. You can see the progression in my journals. I remained "high functioning" to everyone around me, but just a disaster on the inside.
Stop now. It's worth it. Life is waiting. Don't put it on hold another 20 years like I did.
