Glad u got some sleep. yes codeine is a miricle I take vicodin and soma as needed, mostly at night when i need to sleep. I have tried everything, including neurontin, and it did not work for me ( i got paralysis form it.). However, my mom had diabetic neuropathy, and she was on a large dose of it and it did help her pain. It has side effects, it can make u drugged out worse than any codeine or vicodin ever would. that is the problem with most anything that relieves pain, there is always some side effects.but if the neurontin works, that is wonderful. No it is not addictive, but if u get on it , do not stop it abruptly. U have to taper off. Really, any heavy duty drug u take, generally u must taper off of it. It is not just narcotics. The anticonvulsants are being used a lot for pain control and for the bipolar person. But they have some nasty side effects and cannot be stopped abruptly.
I assume u have tried melatonin for sleep? But like i said, until u get the pain under control, the only thing that will help u sleep is probably a hammer.
