I've seen an episode of Drug Inc. about ketamine, and would urge you not to try it. From what I recall, it's INCREDIBLY DANGEROUS!!!

Why don't you look into alternative treatment for depression such as amino acids or herbs like St. John's Wort. Both work by increasing the neurotransmitters in your brain so you feel happy.

I have bipolar 2 and was on meds for 13+ years, went off them due to nasty side-effects and now use amino acids to control the depression and the natural mineral supplement lithium orotate to control the hypomania. I've been doing this for over 9 years with great success.

My philosophy about mood disorders like depression and bipolar and anxiety is that our problem is that our brains aren't able to produce enough of the needed neurotransmitters to keep our moods stable and calm. I view it like a diabetic needing insulin.

Here are some helpful articles on the subject along with a brain function questionnaire showing the emotions and feelings related to various neurotransmitters and the amino acids used to produce them.
