I also suffer from RLS which I was told attributed to the insomnia. Last night I took my first and last dose. I experienced an onset of very irritable RLS, and was extremely dizzy and my mouth was so dry that I had a problem swallowing my saliva but had no problem drinking or eating. I did fall to sleep for 6 hrs. I woke this morning feeling lightheaded and dopey along with that my right arm being numb and tingly. Has anyone every experienced these type of side effects?
