well alcohol is a vaso-dilator...so when the alcohol is gone from your body..it may cause slight constriction of your blood vessels..thus causing higher blood pressure...nicotine might do something similar but dont know..

but anyways...SWIM always has these visual phenomena happen..sometimes they are very 'there' after running(which would raise his blood pressure?) or doing any kind of manual labor..

would seeing little lights 'flying around in the sky' count as phosphenes..they look like little fireflies everywhere..and he says he can focus on individual ones..

its seems to have increased since SWIM started taking psychedelics..and now it happens all the time to him...he likes it though..its like the psychedelics have left their mark on his vision..but hes come to really enjoy it
