Apparently ketamine is beneficial for unipolar as well as bipolar depression and produces effects in hours rather than weeks like regular antidepressants. I found the stuff on synaptogenesis particularly interesting.
I wouldn't take it or recommend it, simply because of what Special K (not the cereal) can do to a person, esp neurologically.
I've seen the article. Hallucination is a serious side effect. However, as a treatment of last resort it sounds promising.
I've tried ketamine and it is horrible. It causes withdrawal from people around you then sleep. It is a horrible way to relieve depression. A much better medication is 6-APB.
