Depression
"My doctor had me try this after several other current anti-depressants failed.  It gave me bad nightmares every night for the three weeks I tried it.  The last night I took it, my dog (who sleeps with me) was frantically licking my face to wake me out of my nightmare. That was enough.  I then went to an old medicine, imipramine, that has proved effective in controlling my depression and anxiety."
