Sudden stopping is definitely not cool. I accidently missed a noon and bedtime dose because of my husband being in the hospital. So it was almost 12 hours before I remembered I had not taken my medication. I was sick at my stomach, horrible headache and felt as if I had the flu. The doctor said to never stop this kind of drug suddenly.

Mrs. D should be able to answer this soon.

I'm glad your back isn't hurting.
