Yep cold water extraction would be ok if you wanna take more than 6. I've heard somewhere that you can take up to 3000mgs of acetam but I'm not sure. I just always do the cw extraction anyways, it doesn't take long...
hell yeah you can indeed, i ate some pills containing the exact same thing today, only had three though but i drank and smoked aswell so it ended up being a mad chilled day with friend at skate park hahaha, even managed to do some shit on the board i usually wouldnt try.
