Hi, my neuropathy pain is throughout my whole body as I have many forms of it. I know what you mean about it starting in later afternoon when it ramps up and tortures you all night. I take gabapentin and was on a very high dose and it was causing weight gain and daytime sleepiness. So we have reduced the gabapentin and added hydroxyzine which helps with the itching and burning. I love that it helps with that deep itching that you can't scratch. It hasn't helped with the horrible lightning bolt pain I get, but the gabapentin will have to be adjusted. It is critical to realize taking gabapentin and hydroxyzine together causes major sleepiness and is why I only take the hydroxyzine at bedtime. But it is not for everyone and would need to be scrutinized by your doctor for your individual health concerns. I'm severe enough that I have a DNR and quality of life is all I care about. But I am enjoying blessed sleep.
I hope you find answers and treatment appropriate for you. God bless!
