Got through my 2+ hours of dentistry this morning with a persistent application of the Dune Litany Against Fear, which for some reason really works for me? Now I am very tired - was skeery and adrenal about it last night - and am tucking in with a pot pie and the second half of Neil DeGrasse Tyson's Cosmos series, cause he's my boo.
