Thanks all, I've had only three unilateral treatments so far and I already feel better than I did on Seroquel, which was the most effective drug for me. This is the first time in over a year that I've had moments when I felt anything like normal, and I had forgotten what it was like. A few days after each ECT treatment, the effect starts to wear off a bit and the depressed feelings start to come back, no matter how much I try to prevent it. The contrast underscores how bad it was, and I think it also goes to show that I can't consciously control this depression or force myself to "snap out of it." Still, I feel better than I have in a long time, and if all goes well the effects from the ECT should linger a little longer each time, until hopefully I get well enough to make the transition to maintenance treatment and start living my life again.
So far I haven't noticed any important memories missing yet, the only thing is I feel a little fuzzy now and then (but no more so than I did due to the depression) and sometimes I get these deja vu feelings, but I'm not sure whether those are real or I'm just imagining them because I'm afraid to forget things.
