I have some sleeping/anxiety pills that also contain an anti-histamine that I was taking before I started smoking cannabis (which by the way works better than my anti-depression meds). The bottle says to take between 2-4 pills before bedtime so I took 3 cause I'm a big guy. Well the next morning I was stoned out of my fucking mind! It wasn't until the next day that I felt normal again. Best day of school ever.
So these are the sleeping pills with benedryl or diphenhydramine? Just double checkin'...
Anyway, check the dosage on the back of the pack. Those are more than likely 25-50mg of the active sedative.
Dosage is a funny thing with those. Tolerance gets build real fast and some people have a much greater sensitivity towards the active sedative. I've had friends take 2-3 on an empty stomach and say they were fucked up, meaning "Hey, these may have some recreational quality."
You were fucked up the next morning, huh? Like still sorted sedated? Gotta learn timing with these things. I personally didn't need anything more to pass out in 8am organic chem. Just wait until you do a higher dose, and you're falling asleep with your eyes open and talking to people that aren't there.
I'm a skinny guy like ~130lbs, and I remember when 250mg got me real messed up, but a month later it took twice that for less effect. It sucks. It was pretty fucked up to snap out of it for a second (for like 5 seconds you'll go delirious), and realize I was talking to a pair of jeans.
