PS. What is next? Do you have migraines or cluster headaches and take a triptan like imitrex or Maxalt? Guess what, these are Seritonin Agonists
S-Adenosyl methionine (SAM-E) is a supplement used for both mood elevation and to treat pain from arthritis. 5-Hydroxytryptophan (5-HTP) is a supplement used alone or in combination with valerian and melatonin to stop insomnia. It is a precursor to Serotinin and is also used in Europe to treat depression. So how long until that herbal sleep aid becomes an excuse to take your guns.
And I am not even going to start with all the herbs that are Monoamine oxidase inhibitors and could concievably be considered psychotripic.

The simple fact is that these drugs are often prescribed for conditions that have nothing to do with one's mental health!
