a) not that I noticed b) that weed from yesterday isn't active in your system anymore - there may be traces of it still, but that doesn't mean it's still affecting you
i duunnnooooo.....my friends friends grandma's ex-boyfriend took 5 of em when he was stoned. then his dick fell off. sooo I'd be careful with that stuff if i were you.
I smoked a gram last week and then took 3 tylonal w/ codiene and i was fine. I sleeped all day the next day, but nothing bad happened. So with regular tylonal your sure to be fine.
