Works well... Almost too well. Lots of anxiety at first portion of the dose, images 'pinch' then pull apart. Mid dose, minor chest pains and anxiety is lowered a little; slight change in image color while still keeping previous deviations. Thoughts become slow. Towards end of dose, images melt/wave dramatically and trail. Finishing thoughts are impossible--even simple ones. Can't speak more than 'ah' and 'eiy' sounds. Done in quiet, black light illuminated room full of black light posters, meditated and used condition dose prior.
