I have suffered with depression for most of my life, although it was only recently that I figured out what it was. My father and both of my aunts have it, and my maternal grandmother and mother have both been diagnosed with SAD.
I think everyone on that list (including myself) have tried medication for it, but I think only one of my aunts is still currently on the meds. We all have varying reasons for not continuing the medication, and I can go into more detail as to why if you'd like, but for now I'll just answer the question you actually asked.
