I used to eat quarters all the time. you'll be fine. all it dose is make the visuals last longer. You know how when you trip on shrooms you feel funny for a while then you start seeing visuals then drop back down to just feeling weird. This will just make your timeline for visuals longer.
The most i have ever ate was 10.5g. I ate my Q but my friend bitched out and only ate an 1/8 so swallowed his leftovers. I feel after 5g It doesn't really do anything different except increasing how long you trip.
Oh I don't do that any more because i noticed when i was doing supper high doses and i looked into the mirror i would get depressed in the morning. something about the mirror when you see yourself that makes you think about all the shit you fucked up in life.
