Its bad advice to not CWE. Always CWE when going significantly over the recommended paracetamol dose. After all, why leave in a nasty, harmful chemical that does nothing for the high? because its easier not to bother? it easy to not bother to use a crossing to get to the otherside of the road...its also easy to get ran over by a bus.
Ive went into more detail in another thread on this so i wont repeat it, if anyones bothered(unlikely.lol) it should be easy to find.
SproutOnSmack's advice is imo the way forward. Id also have a anti-histamine at the ready incase your sensitive to codeine.
