Craziest trip for me: I was driving to Atlanta from NY 10 years ago to register my car there, I left wed. night with only my 13 year old brother for company, got a ticket for speeding and got to Atlanta at 6 am. Spent the day hanging out and then headed back that night with only an hours sleep and needing to get back to NY for shabbos. So as soon as it got dark, I feel exhausted, and keep needing to pull onto the shoulder for catnaps. So I took some nodoz, but that didnt help. So by the next truck stop I asked them for something that would wake me up saying nodoz didnt help. They said yeah, it never worked for me, try this and gave me something called "black Ice" an over the counter natural thingie. WEll I took it, and 20 minutes later pulled over for another nap. Next thing I know, I am driving in the left lane, and my mind seemed brain washed, my mind kept telling me "nothing is true except you can slow down under 60 or go over 75, at which point I realized that this is insane but couldnt seem to get out of this mode for what felt like hours! After I managed to "deprogram" myself I realized I was driving like that for 5 miles based on the mile marker where I pulled over for my nap. Ever since then I avoid all those "natural" pills. Although for the record, A friend of mine, who I told the story to purposefully tried to take no doz and black ice together but did not get any reaction.
