Hi and Welcome - so you are 23 days off vicodin and having these symptoms? How high a dose had you been taking and for how long? If you are having blurred vision and confusion I would encourage you to seek medical care asap - I highly doubt that is still from vicodin withdrawal and you may have other issues going on.
Usually the worst of the withdrawals is the first 5 days then you would just feel weak for a couple weeks. What you are experiencing is not normal.
