Please support him. Please let him know you are always there for him. Please have boundaries (including no smoking inside your home)
and please do not make a thing of comparing him to uncle or letting him believe he is similar to that poor man.
also. Remember ADHD men are much more likely to die of misadventure or suicide than their NT peers. And that risky behaviour is also more likely. More likely to abuse drugs and alcohol and take stupid risks.
if you haven’t already - look into “spikey profiles”
Remember neurodivergent kids may be up to 30% delayed in some areas of development. Therefore he is not really 19yo in all areas of his life. He may be more like a 16, or even 15yo.
Listen to him. talk with him. Don’t judge. Don’t criticise.
does he play sport? Does he want to travel?
Does he have his driving licence yet?
are there little or large life milestones you can coax him towards? Otherwise you may have to patiently wait until he has taken some time “off” and / or until his school friends start to move on.
tbh I’d be encouraging my child to take some time off overseas. Get a different perspective on life.
btw Elvanse should not mess with sleep if taken early enough in the day. Ie if he takes it at 730am it should have worn off well before bedtime.
However ADHD does mess with sleep. as the mind whirrs like a whirling dervish.
Melatonin can help and the doctor can prescribe it to adhd patients. Which is better than abusing drugs to find sleep. It can also be bought online. Most of my friends who purchase it get brand Natrol in a slow / extended release format. Start low.
meditation has also been recommended. But I can’t (won’t?!) meditate so cannot recommend it myself!!!!
NOTE he should not drink or take other recreational drugs whilst taking Elvanse. And ideally at least 2 days break before / after consuming alcohol or other drugs.
has he learnt much about adhd since his diagnosis? Worth considering adhd specific coaching or therapy if you can afford it and if he is interested. (No funding on the nhs). There are adhd charities that run helplines and support sessions.
(adhd mummy here with adhd kids incl a younger teen)
Jannine Perryman is a renowned adhd advocate and adviser. I attended a virtual parenting course run by her when my first child was diagnosed. It was an amazing lifeline. Worth asking her (via LinkedIn or other social media or her website - adhd wise) if she runs any courses which might be helpful for you or your son. Or if she knows of any.
she starts by explaining what it is and what it is not. What may be helpful and what is nonsense. Helps you create your own toolkit for dealing with this different brain. All based on real life experience and with scientific backing where available. Highly recommend.
