Oh my gosh, I was starting to think I was the only one!! I've said soooo many times that I just don't understand why I started blacking out on what I don't consider to be very many drinks. It's like at the end I could drink LESS (but was drinking more due to drinking past blackout).
All *they* talk about is building a huge tolerance but I felt mine was decreasing.
The liver's impaired ability to metabolize or break down alcohol is referred to as "reverse tolerance," and is very common in late stages of alcoholism. It typically alternates with episodes of high tolerance, the latter of which often include experiences of "drinking ourselves sober."
Reverse tolerance often indicates that there is damage to the liver caused by heavy drinking that induces a higher BAC, and then leads to a buildup of fat and scar tissue.
