Naltrexone Isn't this for alcohol’ abuse? I do take Gabapentin 600mg 3 times a day. My Primary would only write 300mg twice a day, but neurosurgeon upped it to 600mg twice a day due to spinal injury. Finaly my pederast changed it to 600mg 3 times a day. I'm bad because sometimes or most times I forget or fall asleep before I take it. It helps most of the time but some days nothing helps but to sit down until pain goes away. I asked my Cardiologist about test he had me take that said high grade stenosis in and 50% stenosis in Tibal if that could be my problem causing legs to feel heavy after climbing steps and foot pain. I am having less of these pains with the meds but still somedays it does come on, can't tell when or why, sometime think weather cold, damp may bring it on but not sure
