This drug is known to cause several serious problems. I have a very
good friend who was given Vicodin by her family doctor (MD) simply to help her
sleep at night and she quickly became addicted to it. It is more difficult
stop the addiction than the addiction to heroin but she was able to stop by slow
withdrawal. It took her about three months to do it.
I would go back to the doctor who prescribed this for you and let him know
what's going on.
