Speaking from personal experience, anti-depressants cause flat emotions. Being off Paxil, an SSRI anti-depressant has lifted a load of flat feelings that I carried for 14 years.

If your therapist thinks you are deficient in serotonin, try taking L-Tryptophan. Source Naturals make a 500 mg tablet that you break in half to reduce the dose. I take 500 mgs twice a day. I can tell I need the L-Tryptophan because I can tell when I am late on a dose. It has a 12 hour half life so you need to take it twice a day.

btw, L-Tryptophan is an essential amino acid that is the precursor to 5-HTP which is the precursor to serotonin, melatonin and another neurotransmitter. It is in dairy, meats, and other foods.

It leaves your system quickly so it is not a big commitment.

I would recommend to just about anybody to try to avoid anti-depressants beyond some of the low dose anti-depressants for PCS headaches and insomnia.

My best to you.
