Withdrawl.

So my nurse called today and I told her about forgetting to take my Oxycontin the other morning when I fell back to sleep. I told her I was aggravated all day and had cold like symptoms she told me I was going through withdrawal symptoms and she said if it ever happened again that I have to take my break through every four hours until it's time to take the night Oxycontin tablet because the tablet starts to come out of your system after twelve hours so I won't miss that tablet again.
