To echo @mugglewump I got through uni with undiagnosed adhd - but it was the first time I realised I wasn’t like other people. Don’t try to get his life standards to those of other students - it just won’t happen and will cause him stress and shame (and worse dibilitating anxiety/ depression). Do get used to the idea of adhd tax.
Things I did in uni that helped me survive -
- I would buy months worth of underwear and cheap clothes when I hadn’t done laundry, and I would take back two suitcases full of dirty laundry each term which my mum would help me do.
2.I only used disposable plates and cutlery and only ate microwaveable ready meals and unhealthy snacks. Luckily there’s more options for healthy ready meals than when I was a student. Worth getting him his own mini freezer for his room and stocking up on meals each term - because he will leave anything fresh to go mouldy.
3.I didn’t turn up to boring lectures and seminars (which was most of them since I was doing a boring course). I did quit all my jobs and do extreme cramming every exam time.
4.I had 3 part time jobs which gave me structure and allowed me to not have budget financially. My favourite jobs being bar work and other high stimulation environments where there was lots going on. Also had a job at the uni office in my final year which required a lot of responsibility and high levels of executive function - wouldn’t recommend as it really damaged my self esteem despite how hard I tried at it.
5.I joined and quit all the clubs and hobbies - this was the best aspect of uni for me. Let him try everything - that will be the most valuable thing he can get from his time there - the space to learn what he enjoys and is good at. No shame in quitting too as he’ll have learnt what he doesn’t like/ isn’t good at.
6.I had days when I didn’t get out of bed and just stayed in my room not eating, watching tv or just being a complete slob. I allowed that with the only rule that I could never have two of those days in a row (or it’s very easy to lose weeks / months to adhd burnout). These slob days are needed to avoid burnout as they are an indicator of overwhelm - not advisable to just push through them.
For ADHD being persistent is more doable than being consistent. As long as he gets up and keeps it moving every time he falls off the wagon, which will be a lot, he will eventually get to where he needs to be even if his route is not linear.
