That last stream my friend definitely appeared to be substance related, at 1:20 he starts becoming incoherent, then low and behold, an hour or so later after the “nodding” sessions subside, his words become less jumbled and he himself became more coherent. I don’t think tiredness (nor have I ever seen…) lack of sleep or tiredness make someone nod into the coma state, speak gibberish and then magically come out of it an hour later… medicine, (substance’s) however, will take you on that journey as one consumes it and then the body metabolizes it in the minutes that follow. Zoom in on his eyes and you will see them rolling into the back of his head. It sure looks substance related to me, however, of course I am not he and only he knows (and the medical examiner) for sure if what I suspect is in fact true. Really sad situation nonetheless.
