Stress is a factor in pain levels and I know from other posts that your home life can be stressful, can you set some time each day to concentrate on breathing exercises to calm you down? this may help with the pain - although with children in the house this won't be easy(I speak from experience) .
Have you tried some of the supplements recommended on this board, I didn't for a long time but have been taking some and found I am more alert and more in control of the pain ( although I decided to switch from Gabapentin to Lyrica a few weeks back and was almost tipped over the edge).
I wish you luck in finding meds that helped - I have been prescribed tramadol for breakthrough pain and it has worked wonderfully for the moment....... But as we all know this horrible condition has a way of getting through all the pain barriers that we use
