Check with your Doctor about taking more Gabapentin. I was taking 4 of this drug or 1200 mg. every night, but it made me sluggish in the morning. My doctors here in Dallas, Texas say I can take 1500 mg. a night. This is great for pain if you take enough.
I have begun taking a healthfood medicine called Omega Green.com. It is made from the HEMP plant. (they make ropes out of it. It is a first cousin to the marijuana plant, but is legal and doesn't cause the craziness. I take a pill twice a day, and have had NO PAIN for 6 weeks!!! Our military uses it in liquid form for bumps, bruises and muscle energy. The pills are something new. They are not sold in the store here as yet, only on the web.
Hope this helps.
