Gabapentin
"I just started taking this medication as a preventive migraine treatment this month/August 2012.  I am so impressed. I did have one migraine starting and what is usually a 10  on the pain scale was only about a 3-4, and all I did was take a Percocet 5mg for the pain, got a really hot shower to relax my muscles, took one of my Imitrex Nasal Sprays, laid down, went to sleep and it was totally gone when I woke up in a few hours. YAY! Another positive for Neurontin for me is that I get a lot of neck, shoulder, back pain and with this medicine I have not had to take additional pain pills (Vicodin, etc.) as everything feels 'muted' and very tolerable.  Also, I have cut down from 10 mg to 5 mg on my Ambien and I am working to get off this."
