I, too, start to get really talkative. I also start talking very fast, and how I pace my words becomes erratic. It tends to confuse others for the first 20-30
minutes of my high.

Also, if I close my eyelids there is this little jittery thing goin on... not really closed-eye visuals, just kinda like very rapid flashing... that's another way I can tell.

Normally I don't worry too much about actively making sure I am high, it's pretty easy to tell <<
