You're doing too much. First time I went to IV some smack, my friend about shit brix when I dumped the whole bag in the spoon... I was used to snorting 2 bags at a time. IV is WAY diferent than snorting. I IV'd a sixth of a bag and it had me nauseous for several hours. HYdrocodone and codeine have different pharmacokinetics, you *could* get sick off of either w/o getting high, especially if you didnt use a CWE or a bad one.
