I am taking Citalopram which works brilliantly for me and is really fast acting, but I do think that it affects dd a bit, so I am (after consulting the GP)taking half a 10mg tablet a day. It just stops me feeling as if I have spent the whole day dragging a juggernaut. My GP and I went through The "Medication in Mother's Milk" book by Thomas Hale. Sertraline is supposed to be OK as well, but My GP reckoned Citalopram was a more effective product, It certainly seems to work very quickly on me.
