The NIH is doing research on DXM which has, as I understand, yet to show promise for its use as an effective treatment for SD. Anecdotal reports on a BB are fine, but if you read closely you might realize people on these medications are also seeking out various other treatments - i.e., perhaps the drugs do not currently provide significant enough help. So I'd hesitate to say they "work" just yet. And this is where NIH comes in as they are equipped to conduct objective studies.Other research going on at NIH will also hopefully lead to the development of additional potential treatments. If you are interested, perhaps you could consider participating in one of their trials. Their research is crucial! And it's not about Botox...
NSDA supports the work of the NIH so I would encourage you to attend the next symposium on May 5 '07 in White Plains, NY where you will hear updates on the latest research on SD.
