Op, I usally do 45 10mg norcos in a single dose, with 45 pills I use 150 ml of water, you honestly should use prolly 80 ml.
To laid, the bare bones of cwe is that apap is not very soluable especially in cold water, the apap basically wants to stay a powder form while the hydrocodone or any opiate particles are very soluable in water, when u filter u get left behind with a lot of apap powder, filter twice to really get the most out of it.
