absolutely....I have suffered with chronic nerve damage down my legs due to a broken tail bone 10 years ago. Although I usually take nothing for the pain as to have my brain adapt, aspirin once in a while, I was prescribed this Oxy..?...small green pill for my chronic, awful pain. Took one last night before bed, and....I NEVER closed my eyes or slept all night....Is this a side affect of this medication?...If so, I will NOT be taking another one. I take excellent care of myself, my health....so, for me to even have considered taking something more then aspirin to help me get through a nights sleep is huge for me...Any ideas?
