Cannot cope with nightly shouting

[Arghteens]

Argh! Have just had the latest in almost nightly big shout fests with teenage son,
I don’t know what to do but something has to change.
He is not into drugs, drink, skipping school or anything awful,
He has ADHD and when meds have worn off things are really bloody difficult. Constant answering back, shouting, swearing, banging doors ( so plaster comes off wall), demanding. Very stressful and upsetting for all of us, but more so for his younger sister.
DH is lovely but doesn’t cope with stress well and has recently been discovered to be drinking too much regularly. Think 3pm seen by daughter with bottle of wine regularly. Lied about it 3x that I know of. Has decided to “stop”. Cannot go a week. Oh and work full time.
Please send any ideas of how I can change things for the better! So far taken x box for 2 weeks as feel he is so angry lately.

He does talk when calm and we listen. It’s more that he cannot not say things he thinks, no matter how rude, inappropriate, how others are feeling etc.

Can his meds be tweaked, if his behaviour changes when they wear off maybe he needs a different dose? Or does it make him feel ill when they wear off and he may be less able to control his emotions because he doesn't feel great (apologies, I don't know how ADHD meds work or the side effects - maybe tiredness or nausea?) I'd ask the GP. We've had issues with aggression and swearing and it's rooted in anxiety and feeling like they're not in control. Could there be something else underlying the behaviour - worry about school, exams, friends?
