Yeah, you burnt nearly all of it.
Look into a GVG, sandwich method or infusing the DMT into some type of smokeable herb. Conduction type approaches, especially applying heat directly (like with a nail), definitely diminishes the experience quite a bit.
And what anrchy said, 700mg ..hehe... extreme multiple-times-overkill; even 40-50mg properly vaped, taken in 1-2 tokes will completely shut down your world, there wouldn't be any realization of 'disconnection', no talking, no nothing, no single thought, just complete union with the mystery ..hehe you literally wouldn't know what hit you.
With that said, im glad you and the lady had such a profound experience.
