Pregabalin
"My whole body would be on fire without Lyrica. My sensory neuropathy is so bad I wouldn't be able to eat most foods without terrible reflux pain that would burn my throat and face. 

It does cause fatigue (build up slowly) but it's a trade off for quality of life. I have none without it. 

Lyrica has been the only drug that works for my small fiber neuropathy that didn't suddenly stopped working for me. 

I've had to increase dosage over the years. I currently take 350mg day, targeting 400mg."
