i don't even know if a sitter can really "fix" datura. i crushed a coffee pot in my bare hands, ripped a bunjie cord apart, and destroyed a toilet in a four hour period[among a host of other strange shit, i ended up naked talking to myself under an outside stairwell at one point and i can't remember at all how i got there or what happened after that]. i'm normally a really happy guy, drugs or no drugs, and i wasn't exactly filled with malice or anything: i just had no fucking idea what i was doing. i'm even somewhat familiar with the dilerient feel and it was still more than just a little overwhelming. imagining the kind of things that could happen with someone who'd never played with other dilerients and who had a tendency to "spook" sounds like a really horrible time that'll probably result in jail time ;[ even though it can be very challenging[bordering on not fun, same with datura], i'd suggest doing diphenhydramine[benadryl, sleep aids] before datura so you'll know what to expect as they are pretty experientially similar. dph doesn't come with that inability to feel pain or superhuman strength so it's alot safer for anyone who might be around and for yourself. the confusion is still there, you just feel so weak that you're almost incapacitated and will typically end up in a shivering ball on a couch or bed. although the come on for dph always felt like the euphoria from an opiate's come on, which was always nice, the rest of it is just so tasking in everyway that there's little motivation to use it. the next day brings unquenchable thirst, speech patterns that make you sound like you're braindamaged, a brutal case of the shakes, incessant headaches, itchy skin, and general bodywide exhaustion. hurray!
edit: ya liteage is right on about that too. it destroys your vision for a while and you don't really remember much about your trip so you'll spend the next few days wondering what happened that night and how it's possible for you to feel like that
