hello,what are you refering to when you say "daydreaming"?We don't have to forget how maladaptive daydreaming desensitize dopamine receptors. People who went through high stress at some point experience excessive daydreaming which acts as masturbation.
After we stop daydreaming, the first days boringness will come and your mind will push you towards daydreaming but we have to put resistance.
Of course, having high dopamine levels will make easier for a person to switch to present moment. I noticed B1 helps knowing that increases cognitive function.
During next days I will see how it is with 1.5g of B1 and 150% RDA Magnesium.
