Yep, me too. I started three weeks ago. It's truly unbelieveble. Here's how much satisfied I am with the results: I would gladly trade 10 years of my life to continue like this than live them as miserable as I was, plagued with rumination, anxiety and horrible attention control.
I had a very nasty depression. Extreme mood swings. From very low up to neutral and back. (I never had manic episodes) Up and down, up and down... It was maddening. And extreme rumination. I discoverd acetylcysteine by accident. I didn't know it could help with depression. I felt its effects within an hour. I immediately went on the internet and searched for "acetylcysteine and depression". That is how I found above article. The internet is full of articles about the efficacy of NAC in relation to psychiatry. I used it for about 6 months. 3 * 600 mg daily.
600mg, water-soluble, everyday before lunch.
