I am going to chime in. My ex did not fit in with the classic portrayal of an addict or drug abuser. He was/is high functioning. He is great at his job. Highly educated. Very smart. His friends are all law enforcement! Yet he was drinking in secret. I know this only from 5 years of credit card statements. I suspect drugs because of weird habits i never noticed till i learned the signs (constantly purchasing immodium, always running errands that made no sense) and saw the cash withdrawals from bad neighborhoods.
