I've dealt with RLS for about 25 years but am new to this website. I've found the RLS Foundation websites (rls.org; rlsfoundation.blogspot.com) and publications very helpful over the years. I have no connection with the RLS Foundation (RLSF) other than my $35 annual membership fee. I tried to search out references to RLSF here but am still learning how to effectively search and found only a few references. Please excuse me if I am duplicating info you already know.
RLSF publishes a useful quarterly update (" Nightwalkers") . Spring 2019 included articles on augmentation treatment (promising study with the drug ecopipam); methadone treatment; RLS triggers, and; medical cannibas and RLS. They host free webinars ...next ones are June 20, 3:00 PM Eastern Time on "Medications for RLS" and July 15, 3:30 ET on "Basic RLS Pathophysiology." The website has further details and registration info.
I found the posts and info here very valuable and hope I can return the favor.
