Pain tells our brain that there is a problem we need to take care of--pull our fingers out of the fire, get off that broken ankle, etc. With neuropathy, the nerves are sending an inaccurate message. The pain is not a signal to stop walking. It is useless information, so we can retrain our body to ignore it. I have been using the breathing and visualization techniques I learned in LaMaze classes 35 years ago for childbirth for all kinds of other painful situations. Basically, I just try to think about something pleasant when I hurt. (Actually, I hurt all the time. At any gven moment my hands and feet tingle sort of like they are asleep, but sometimes the pain is worse than others.) I try to find something that will fully engage my mind like a good book or movie. Of course, it doesn't always work. Sometimes I will get a stab of pain that makes me gasp or wince, and the people I am with will ask me if I am OK. But generally during the day, I ignore the pain. When it is more intense, I start deep breathing LaMaze style. Trying to sleep is a different problem, because there is less to distract me. My neuropathy may be less severe than what some people experience. There isn't really any way to know what kind of pain someone else is in, so it might be if I had a more severe form, I wouldn't be able to tune it out. People at a pain clinic could probably teach you some relaxation and visualization techniques to try. You would have nothing to lose because these techniques have no harmful side effects, and they might reduce your pain. The supplements I see mentioned most often for neuropathy are the B vitamins. Of course, it is important to always check with the doctor about all supplements because each person's medical history is unique.

I have a friend who has used a Tens unit for back pain and likes hers, but I have no personal experience with one. I do not know how well they work for neuropathic pain, but it is worth exploring. You are probably already monitoring this, but if your worst pain is at work, there may be a trigger in how you are sitting or standing. After three years, you may yet see some additional improvement, but I think you probably are at the point of finding coping strategies, rather than cures. I wish you well as you try different ideas.

I mentioned that some anti-depressants help neuropathy pain.  A new study has looked at Cymbalta specifically for chemo-induced neuropathy, so that might be another option.

I think you need to give most new drugs a while before you know how effective they are.  Depending on the dosage your doctor started you on, your doctor maight also be able to adjust your dosage to give you the best combination of pain relief without troublesome side effects.  As you point out, one big advantage of Gabapentin is the low cost.  Thanks for checking back in with us.  I hope the Cymbalta/Gabapentin combo makes a difference for you.
