Amitriptyline
"This was the first medication I was prescribed once I was finally diagnosed with vulvodynia. I have experienced a tremendous improvement after two weeks of taking this medication. I was originally started on 10 mg with no relief after 2 months of use. My doctor increased it to 50 mg last month which has really worked. My personal regimen includes  50 mg amitriptyline at bedtime, Estrace topical, B complex vitamin and alpha lipoic acid. My pain went from a 7 to 2 in a matter of two weeks. It makes me constipated, so use fiber supplements daily. I was very drowsy initially, but you will adjust in a few days. Exercise and a healthy diet has greatly decreased the side affects (sleepiness, weight gain, constipation) associated with this drug."
