Why don't you just give some 5-HTP a try. It is quick acting where-as SSRIs take weeks to show the true effect. 5-HTP does not cause flat mood.

Your brain already uses 5-HTP. It just may not have enough.

You can quit 5-HTP in a day with no problem. I miss a dose from time to time. I notice a difference and redose the next morning.

Start with a 50 mg dose am and pm. if you do not notice a difference within a week, increase to 100 mgs. I doubt you will need more than 100 mgs twice a day. But, some need up to 500 mgs twice a day.
