I've had depression since grade school. Some years ago I got a virus or something and was given three big azithromyacin pills to take, one a day for three days. The depression went completely away for three days. I had a ton of energy, I felt happy, cheerful, outgoing, I could think clearly and remember much better. Much more relaxed and optimistic. Like everything was fixed.
The third day I took some psyllium fiber and it all came creeping back.
