When I was in college, we could always tell when members of the football team started using because otherwise pleasant guys would almost over-night start acting out and became aggressive, even off the field.
You may want to google signs to look for - it can be right under your nose and you wouldn't know it. If he's taking anything he says "is just a supplement" - check it out.
Whatever the cause, I'm glad you're reaching out - it's a lonely place to be and at the very least you want to be understood and validated. I get it.
I meant to add alcohol to this list. Do you know how many "functional" alcoholics there are? They are often good at their jobs - one of the best in the field - but at home it's a different story. And if he's charming in public, it's much harder on you. I know somebody who is well respected in his field, has a life-long drinking problem and is very good at hiding it. At home, if he needs a drink or has crossed the line to "one too many" it's as if a light has been switched out of no where. A drinking problem - or drug problem - is a PROBLEM whether the person is falling down, passed out or a "simply" causing a relationship to decay - there are many reckless, destructive addicts who aren't "obvious" or text book ... and they're the ones that can cause the most trouble for their loved-ones.
