neuropathic pain
"I went to a specialist in pain management.  300mg seems like way too much of a starting dose. 100mg for 3 days then 200mg 3 days 300mg 3 days etc. Let's your body get used to it. Go up to 600mg 3 times and then stop. If you don't have relief by then it's unlikely you will. My nerve pain from folfox platinum chemo destroyed my nerves in my hands and feet. This gave me about 50% reduction in pain  worth it. Very tolerable site effects. Minimal really. Try but try it right."
