ibromyalgia
"For the past 5 years I have suffered with fibromyalgia, I wake 4 or 5 times a night and generally feel like I have had flu all that time.  I started on gabapentin 100mg 3 x daily for 4 weeks and did feel I had a bit more energy, my GP then put me up to 300mg x 3 daily and it has made a massive difference.  For the first time in years I get a good night sleep and don't feel like I have been hit by a bus when I wake."
