It is important to avoid D1-stimulating activities like computer games in the hours before bed and to gradually lower your dopaminergic tone so you are ready for sleep.
An optimised evening routine starts with a nice hot bath. This will get your tonic dopamine and serotonin levels moderately elevated, which helps with both focus during meditation and neuroplasticity for learning and unlearning.
If you aren't too self-conscious then adding vocalisations to your bath can really boost the mental integration. These are formless humming to move vibrations around your cranium and directly stimulate your vagus nerve and midbrain, which has follow-on impacts on cortical matter and the VTA, which is one of the main places where dopamine is produced.
Sitting meditation is the natural progression from here: you will be relaxed and open both mentally and physically which will make things a lot easier and more productive.
Do not set a timer for your meditation; this will just become another thing to 'grasp' for which will increase D1 phasic signalling. You can set a stopwatch out of curiosity, but there is no finish line to the practice.
The point of this evening meditation is (at least at the outset) to lower your reward-seeking tendencies and to stabilise your dopaminergic tone. The simple guide in the low stimulation page should suffice.
After this, if you are in a deconditioning and cultivation phase, it is a good idea to review the day's writings before bed. These will go back into the couldron of your mind and come out as something new in the morning, ready to be optimised once more.
