i am grateful for the info. if DPH is too hellish for me i might take on sleeping pills so i will be unconscious for some of it. i will most definitely get weird dreams though.
It's not just the hallucinations FYI. It's also somatic (bodily) effects; the body/brain will be flooded with stress hormones and the sympathetic nervous system will be extremely activated, causing panic. Other symptoms prior to losing consciousness will include tremors, hot/cold sweats, shakes, vertigo & dizziness, pounding headaches, intense vomiting, tachycardia/arrhythmia, muscle tremors/shakes, nerve pain, tingling, sweating, aching, burning sensations, the list goes on.
People who take DPH recreationally usually hate it and are occasionally traumatized. And they aren't even experiencing the somatic symptoms at recreational doses.
What you're describing by taking sleeping pills prior is probably along the lines of a "cardiac switch" which is not very effective with DPH as it doesn't typically cause cardiac death. Death would be more likely from physical injury due to seizure (i.e., head trauma) or a seizure-related stroke that is very unlikely unless you already have a chronic cardiovascular illness.
Common sleeping pills like benzodiazepines, or Z-drugs (zoplicone, zolpidem) are likely to reduce the probability of seizure, however. They are often used in hospital to treat seizures. You definitely won't succeed at slitting your wrists by blacking out on sleeping pills as well.
Likewise, modern sleeping pills are virtually impossible to overdose on.
I'd reconsider this method. You might be feeling helpless but its not worth suffering + trauma + potentially debilitating injury only to almost certainly (99%+ probability) wake up the morning after. There are other methods/options.
