I have been taking generic Ambien..(Zolpidem 10 mgs)..at night about an hour before bedtime, for quite some time now, and have noticed that my body seems to release from the weakness that follows my off period, after my meds wear off for the night..The process of wearing off, begins about 6:30 pm with dyskenisia, and then I get a huge spasm on my right knee that encompasses it front and back..This is when the shuffling, and freezing starts

For the past two nights in a row, I decided to take a Zolpidem at 7:00 pm when I am wearing off for the day, to see what would happen..A half an hour after taking the Zolpidem, the spasm was gone, and I could walk without too much shuffling, and the freezing was minimal..I took another one at 11:30 pm, and after midnight, I was almost symptomless

This has happened two nights in a row..What is up with that?..Does anyone have any thoughts on this?
