Hi Bob,Glad to hear you've found something that helps you. There has been a lot of previous discussion about Dextromethorphan, which is the active ingredient in many cough syrups, including Delsym. Most people who have reported improvement with Dextromethorphan have said that it takes a few days of use to get the full effect, if any.
The National Institutes of Health (NIH) conducted a study comparing different types of drugs, including Dextromethorphan, and their affects on SD symptoms. I don’t know if the results are available.
