Hello,
Yes, I have had ECT done before...about 10 treatments, unilateral (one side of the brain). It was during my worst depression, when no medication was working and we were out of options. I didn't enjoy it AT ALL (very scary!) but it worked tremendously. I would get it done every Monday, and I'd feel fantastic for the entire week! Besides the fact that it was an unpleasant procedure, it was a miracle for me.
Of course, I suffered the nasty side effect of temporary memory loss, which was frustrating. Slowly but surely, I got my normal cognitive function back. Despite this serious side effect, I'm glad I went through it because it yanked me out of the serious slump. Without ECT, I think I'd be dead by now.
I had to stop because I started to be VERY ill after the ECT...for about 3 days after. Severe nausea and even vomiting. I thought it might be a fever or something, but it happened for 3 weeks straight, and only after ECT. They tried to give me an anti-nausea injection before the procedure, but it didn't help. I was sad that I had to stop...and I have NEVER heard of this happening to anyone else but me. =/ So I don't think it's something you'd have to worry about.
This all happened about a year ago, give or take. Since then I have had many depressive episodes, and many more med attempts. Finally, about 6 months ago, we found a med combo that worked, and I am doing well most of the time. I would definitely recommend ECT for those who are out of options, but would not recommend it for a first line of treatment. Because the side effects can be severe! However, I can personally say that it saved my life.
This is a very tough decision to make. Take your time, do your research, ask questions. I hope you find the best solution for your recovery.
