Maynard... ?!~ are you still wondering about it  and taking advice..? or is there a report you have  for us .>!?     I'd say one just has to learn to 'slip' under ... a wonderful wave, so lie down or recline in a lazyboy chair.  At low doses (10 - 20 mg) it could be just really awesome closed-eye visuals or the same but disorienting with eyes open.      There's too much in your being to 'surf' if the dose is > 20 mg, so I say  go loose and 'slip' under whatever hits you, dissolve away as the buzzing, warm and wet wave hits...     It can be disorienting in bright daylight for noobs like me ... So I try it in the dark, or at night in  warm, safe, comfy room. A friend learned about dmt by starting to try it only while naked in bed ... !    Or as a 'warning', I'd say it's the 'rush' that's the only thing to be prepared for - so let go ... even if suddenly ( in 20 heartbeats) you feel the 'warm and wet' of what might be peeing-your-pants..! Kind of  like the flight-or-fight response gone wild, you'll be rushing / orgasming and 'dieing' psychologically, so go with it !  (you won't be peeing or dieing !) The rest could be anybody's anything, and NOT (just) scary, it could be everybody's everything... going on all at once, but really good !.    Once you've  learned to 'welcome' and give into the feeling of a huge warm and wet surge that 'buzzes',  that comes on right away,it's an easy 'slip'  .    But ! the hard part is remembering any of it !
