I'm late 40's and recognise that many of my behaviours seeking out that dopamine hit are negative. I have strong ADHD traits and have suffered from eating disorders (bulimia mainly). I still have a very disordered relationship with food but I recognise this and am working on it.
I also like "buying" things. Again I have got much better at this but I've just cleared out 12 bin bags of clothes (my drawers were bursting) some of which are barely worn.
Ironically my other vice is my phone and specifically Mumsnet!
I'm want to try and find other more positive behaviours to replace my current negative ones and retrain myself. I do exercise regularly and I try and read but it's not quite the same.
What healthy habits do you have that give you that positive hit?
