I recall reading somewhere that datura can be cumulative, and having little amounts of the seeds but having them often could be just as bad as having a lot of them all at once. Were you using them every night?
Also I'd like to say that if anyone is starting with low amounts of seeds and increasing in increments to test their effects I suggest waiting a few days in between dosing so that you can gauge the strength that way more safely.

That's a good point you are making Boy. To be honest, i don't really remember, but it is possible...

When I put the harmine in it didn't seem to stir well, it was very sticky and difficult to get in the orange juice in the first place and then the little globs of it would just float on the surface and seem dry no matter how much I tried to stir it into the liquid. I didn't get all the harmine into my mouth until the last few gulps. The DMT seemed to mix in easily. After I was done drinking the orange juice, I could still see some harmine I think stuck to the inside of the glass but I got most of it down. Was a wild experience.
