I did a
wiki search and found that I'm actually on a tetracyclic (mirtazapine) which is apparantly similar to Tolvon.
Mirtazapine helped me enormously with my mood, I felt normal on it for nine months, but after that I started to feel depressed again.
Mirtazapine for the first two weeks pretty much knocked me out as soon as I took it, but that wore off and now I don't feel so drowsy, but I still sleep 11 hours per night.
