Arm 2
Experimental
Placebo Comparator
gabapentin
placebo
Patients receive titrating doses of oral gabapentin twice daily and then three times daily for 3 weeks. Patients then receive a fixed dose of oral gabapentin three times daily for 3 weeks. Patients cross-over to therapy as in arm II at week 8. Quality of life is assessed at baseline and then at the end of weeks 6, 8, and 14.
