Just don't keep asking him..... are you okay ... are you okay ... are you okay it will create weird thoughts in his head.. then he'll start thinking something's really wrong and it will snowball.
hes doing a little better since the movie started, i hope this will continue. he just seems distracted now.
Xanax, Clonazepam, Valium.. do you have access to any of these? if you do.. have him take a double dose.. if it don't just knock him out.. it will at least help kill the trip
if I was on acid and people started handing me potatoes I'd be scared. hell if that happened to me anytime I'd be scared.
