oh shit, a whole eighth!!! 
dude i never eat less than a quarter of shrooms.. you need to eat a big amount of them if you want to get the "true" effects... not just the basal stuff... its not like a pill of ecstacy or a small line of coke... eat a meal sized protion of the things... then youll feel the way your intended to feel on shrooms.. connecting with your self, your relatives, human beings in general, seeing the world in a different but positive light, connecting with a higher level existance.. etc..
I've taken heroic doses and light weight doses, my most intense trip coming from 2g of Golden Teachers that a hippy friend grew. Usually this is a true enough statement, but there are some damn potent strains out there. Start light and if you need, take a little more.
I prefer to take lower doses and just allot myself enough space to smoke a few joints and cigars throughout the trip. Mushroom tea is also great too because it hits you faster and then if you DO want to bang back more shrooms, you can do so without unexpectedly being catapulted into a trip of wild proportions.
