Fishy nailed it, write your condition on both of your arms in BIG letters with a sharpie and freshen it up daily too.
I'd also want it to state "I have SVT, please call a ranger etc for HELP to medical! Just in case you're far away from one of the medical tents (very clean and usually calm inside the med tents, bravo to those volunteers!!)
They do sell a low cost life flight plan on the burningman.com website btw, can save you big bucks if you needed that.
Savannah also nailed it, KNOW where those meds tents are...try to seek them out if you can find the time and do it amongst the many many distractions of fun and what not, hehe....
If you're alone (say for instance out in the open BIG playa) and need help and you don't see a ranger ask anyone, preferably someone on a bicycle to GO FIND someone official looking with a RADIO...they'll then radio for a vehicle to come to YOU and get you the shot you need.
Most people don't know this but I am partially disabled and camped with The BRC Department of Mobility (great wild fun camp located across from Center Camp) and MUCH of this stuff was DRILLED into our heads by our camp leader...man am I GLAD he took the time to do that because my job that first year back (I missed the previous 15 years, fuck!) was to troll the burn in a schweeet lil' gifted golf cart (thank you for the gift of Golficus Carticus Motz!!) for injured, troubled, tired burners as well as drive other non-emergency scheduled "I need a ride to and fro type" disabled burners here n there...and let me tell you....I rescued many many burners that year (2010) and it was busier and busier and became louder and louder as the burn week built up toward man burn night and the whole community sort of became one big heart beat (we were right up front on the Esplanade open 24/7!! omfg!) in the thick of everything....you could "feel" the community intensify until we the eve that we burned the man. I rescued several "troubled" burners that night...no biggie mostly manageable situations (too much fun type stuff) BTW, I do
not want to discourage anyone from going to the man burn by stating this....especially a birgin! It was the best! and so much more...
As for dreams, mine lasted for weeks! and come and go to this day, hehee...thankfully so! I had none pre-burn but countless post burn....I have no cure except enjoy them and create art for the rest of your life kiddo!
Much love, moonrise

I'm the MAN in a truck, burner who is stuck, you're in luck! I'll whip out my BIG tow chain and not charge you, not even one lousy buck!
