What's to be expected? might tylenol (acetaminophen) with codeine cure dope sickness?

No "Cure": What you are probably referring to is the physical withdrawal associated with chronic use of opiates. Which Codeine may make the withdrawal symptoms go away temporarily depending on the amount of opiate tolerance and the dose of Codeine used, the only long term answer is an an assessment by a good addiction medicine doctor. Untreated opiate addiction will kill you eventually.
