I was prescribe demerol 100 mg, lyrica which I will start next week and prozac10mg, I started the meds yesterday and I noticed this twitching in all my extremities and now my neck. I am also on soma at bedtime and still the neurontin, I am tapering down. I am wondring if I am not tapering slow enough. I would like to now if any experienced this before and also has anyone found relief from demerol, it is not helping the pain.
