I'm still on meds.
The ECT helps combat lethargy and restore motivation. It seems to have had a cumulative effect. For a long time I had two good weeks after a treatment before slipping back into depression. With the maintenance over time I got to the point that I was going three weeks depression free. Now I can get nearly four weeks clear. My recent fight with suicidal thoughts came from withdrawals, so it's sort of the exception. For the most part, ECT has chased away thoughts of suicide. I would add, even when dealing with depression these days it's much less severe. The depression I fought before the ECT left me incapacitated, so it's a tremendous improvement.
