Maybe it wasn't rock bottom, but Clare Mannion can't imagine how it could have been worse, finding herself, as she did, drinking airplane bottles of vodka in her closet.
Mannion was no rebellious teen, no exhausted young mother trying to escape the trials of parenthood, no office associate working her way up the corporate ladder by after-hours imbibing with colleagues.
Mannion was in her early 60s, married and a professional Realtor when she began hiding her drinking from her husband.
"I thought I was a social drinker," said Mannion, 67. "Someplace in my late 40s and early 50s, I believe I crossed over that line. It is a progressive disease, and I progressed completely unaware."
A spate of recent studies, coupled with plentiful anecdotal evidence, suggests that Mannion's progression is hardly rare.
A rising number of baby boomers (those born between 1946 and 1964) are turning into baby boozers, with steady spikes in alcohol and drug consumption, of the legal and illegal kind.
The trend is alarming doctors, substance abuse specialists, family members and, frankly, some boomers themselves who wonder how, after decades of problem-free drinking, they're finding themselves in rehab.
A study published in JAMA Psychiatry found that the proportion of older adults engaged in "high-risk drinking" jumped 65 percent, to 3.8 percent, between 2002 and 2013. For a man, that means five or more drinks a day at least once a week during the past year; for a woman, it's four drinks in a day.
