text: i just accidentally gave my 10 yr old son 2 tablespoons of nyquil nightime istead of 1 tablespoon!!!!!!? what should i do?  i got distracted and was giving myself some at the same time and got confused and gave him the same amount.  will he be ok????? i am making some french fries right now to put in his stomach hoping it will help absorb some of the medicine, what else can i do and how will this effect him, please help!! what makes people drowsy from nyquil is the 25% alcohol added to the antihistamines.  it would take way more than 2 tablespoons to cause any toxicity in an otherwise healthy 10 year old.  if he were to take a whole bottle at once, that could definitely be a problem and i would then advise calling your local poison control.  he'll be fine, albeit very drowsy.
