Again, a very difficult question to answer. Happy is relative to life style combined with degree of RLS symptoms. Reasonable sleep per night, 4/5 hours and non sever RLS during the day, support from family and friends being very important, full frank discussions on how RLS effects the individual is paramount. Understanding by others helps tremendously when those 4/5 hours sleep become 1 or 2 per night. So yes, happiness is more than possible, but dependant on these factors and of course our individual determination for RLS to not dominate and interfere to harshly in our daily lives. We all know and are well aware that on some occasions we aren't able to prevent the depressive nature of the syndrome at its worst.
