wow man, thats out of the normal reaction to codeine for the majority of people. i can think of one time when i swallowed the 20 codeine fortes without doing an extraction, was extremely high but had to endure one nasty stomach pain during the whole thing, i was itching like crazy and making myseld bleed at one stage im pretty sure. it was probably the highest ive ever been on codeine - i think it was having the apap and codeine together and not having eaten during the day and knowing my state back then some alcohol very may have been mixed

not advised one bit at all - i did everything wrong i could have.
im glad youre fine from your incident. another great example of why its advised to always have someone accompanying your while youre on opiates.
