Hello,
I had lumbar fusion surgery (L5-S1) back in November, and in my second week after the surgery, I developed severe nerve pain in both legs that lasted all night from about 7pm until the morning. After four nights of no sleep, I went to the ER to see what they could do. They prescribed Lyrica, and I was taking 75mg three times a day. By the second day, I was not feeling the pain any longer, and a side-affect was that I slept better on the Lyrica than I had in months. If you haven't talked to your doctor about this, I would ask about getting Lyrica prescribed.
