I have spinal stinosis (?) and have been in severe pain for over a year. My Dr. gave me Hydocodone/ acetaminophen 5-325 TB to take and said that I could try taking a 1/2 pill in the morning and the other half at night, and when that no longer works for me, I would then need to take 1 in AM and 1 at PM. I was on zanaflex, but it made me sleepy all day, so I don't want to take too much of this, in case it has the same side affects.a
