postherpetic neuralgia
"Diagnosed with fibromyalgia and had tried so many different meds for it without any good results. Finally got prescribed Horizant and have been on it for 4 days now. Started at 600mg first night and had a bad experience . Doc gave me new prescription for 300mg once per day and slowly I believe it is starting to work. My pain has improved a little bit every day and my sleep is improving also. Since it has been only 4 days I'm hoping to see more improvement as time goes by. Doc wants me to stay on 300mg for a month then up it to 600mg. If I continue to feel better I think I will up it after a week and see what happens. I will post updates."
