^ Same here, delirium isn't fun at all (been there quite a few times at the tail end of a proper amph binge), all the physical side-effects of datura make it all the less appealing. Plus it has a pretty low therapeutic index (if you can even call it that, since deliriants have basically no therapeutic value whatsoever) and it is very difficult to get the dosage right due to widely varying alkaloid contents. Overdose results in either a) toxic reaction, possibly resulting in death; or b) extremely delirius state that could last for days, and a myriad of negative after-effects potentially lasting for more than a week. Not worth the risks even if there was some sort of a reward to be gained IMO.
If deliriants intrigue you, however, there are much safer and shorter lasting alternatives out there. Still, not my cup tea - I much prefer having my dreams without being conscious at the same time, thank you very much!
