dont go straight into the 3rd or 4th plateau. i made a mistake of drinking a whole 8oz and smoking weed on it, i was so fucked up i couldnt pack the bowl anymore,and my legs were 1000 miles away. i also had to close one eye to walk which wasnt too fun. Id stick with around 300-500 but thats just me.
also, i drank mine sunday morning and felt it the next day at school. smoking on it makes it alot stronger,and it lasts longer too. because monday when i smoked a joint before school it made the dxm come back,and i was fucked up in first hour.
