ibromyalgia
"Amazing.
Have severe fibromyalgia pain as well as chronic cervical spondylosis, following a failed neck surgery.
Tried everything, was put on pregabalin but it stopped working & so expensive. Dr. switched to Gabapentin (dirt cheap) at low doses below 600mg  just caused sedation did nothing ,but at higher doses 900 mg (at night only) my pain melted away from 9 to 1. No longer sedates me but clears brain fog and restores energy and motivation. It's also done wonders for uplifting my depressed mood (a real happy pill).  Some insomnia, but  I need far less sleep & no longer fatigued. Side effects are some occasional tremors & dizziness , myclonus, when it's time to re-dose, but nothing bad.  A miracle medicine. 
Great for chronic fatigue"
