Edited completely guys, having read the comments on neurotransmitters above.
I seem to have low neurotransmitters in general because I require antidepressants to not have clinical depression - and I’ve had clinical depression from age 8 (I’m now 44).
I currently take 45mg of mirtazapine which I believe increases serotonin, norepinephrine & dopamine at that high dose.
I definitely still struggle with low dopamine - I’m kind of sluggish & have low motivation unless I’m pursuing dopamine activities.
I find dopaminergic activities addictive - I have to make an effort to stop workouts after a sensible time because they make me feel ‘alive’ & often euphoric.
I used to ride motorbikes for the same reason & after that martial arts really helped me stop feeling dull & ‘grey’
I don’t use drugs including alcohol except for morning caffeine because I recognise this addictive personality.
At the moment I’m trialling a 30 day dopamine fast to try & reduce the need for excess stimulation. This means no video games, no porn, limited sugar. Video games & porn weren’t excessive for me, but what I’ve learned about dopamine tells me porn in particular is highly damaging to the dopamine system.
I decided to do this after learning more about neuroscience from Huberman Lab, in particular the episode on the science of addiction.
Perhaps surprisingly I don’t find the physical jobs enjoyable or euphoric. I find very specific workouts euphoric - weight training that produces lactate like drop sets & 90 second rest periods, cardio at 80-90% max heart rate & boxing training or Muay Thai training.
Strength training at 2RM or 3RM with longer rest periods of 4-5 minutes isn’t enjoyable from a stimulus addiction standpoint… but it’s very effective at giving me results.
Having read Christian’s articles on stimulus addiction versus actually getting results I have started following Christian’s recommendations
