I agree with the sentiment that sub-beakthrough doses for 5-MeO-DMT are not the best idea for the first time. I have to admit, that I've never actually broken through, but I've been close, and it felt horrible, especially on the body. I used to love low doses though, especially with marijuana.
Man, it's been years since I actually used this substance. I was pretty much thrown off by my sub-breakthrough experience, but now I've become really interested in it again. Perhaps it's time to re-indulge soon.
Edit: I hope it's okay to make a distinction between a sub-breakthrough dose and a low dose? Because a low dose and a high (but not high enough for breaking through) dose feel worlds apart to me.
