Anyone with experience taking DMT orally. Advice needed

I have Syrian Rue seeds and DMT… was going to start with 70mg dose, how long does a trip usually last, will I be ok by myself if I stay in my apartment? Should I take a higher or lower dose? What has your experience been? I have smoked DMT about a dozen times in the past and broken through as well as many many Shroom trips and a few acid trips.
