nasal spray won't work shrunkenhead. the only zicam product suitable for tripping is the zicam cough max in the pink box.
and thats weird that it seems to be extended release for you mistajeff. thats the first time i've ever heard anyone say that. typically people describe it as kicking in quicker and lasting less time than other products.
and btw, if you do the math according to the packaging, zimax contains just under 400mg. however, i've measured the amount of fluid in the bottle before and it actually contained about 2 or 3ml more than the package claims. i only checked once though. i should measure every time i buy one just so we can know for sure. however, i figure zimax probably has anywhere from 350mg to 500mg in it. (with those being the absolute extremes). my logic is that since matrixx is probably aware of the variation in volume of their product, then they probably will err on the side of caution and include more than the package states typically, if there is an error. so that the consumer isn't shorted.
