If George is suffering from clinical depression (it may be something else) it is not at all helpful to tell him to NOT take his medication. It is obvious that both his GP and psychiatrist have decided that they should at least try him on this medication.
I have been on a combination of Citalopram and Lithium for a few years and have had no problems, they have helped me and improved my health. I am still bipolar but life is no longer one long surreal nightmare - in my case giving up a stressful job really helped.
I took Seroxat about 10 years ago and ended up very ill and almost flying. But just because it didn't suit me I would never advise anybody to avoid it. Always proceed with caution with any new medication.
St Johns Wort is excellent and really does work - but not for everybody, it is not really effective for severe depression.
My psychiatrist also told me to take omega 3 epa capsules - I take two per day.

I wish you well George.
