I had PP after my first son and was prescribed olanzapine. I also took it after my 2nd son at a lower dose as a preventative for a few months (that time I was fine).
Anyway, 2 years on, sometimes I take olanzapine 2.5mg if I'm under stress and feeling a bit wired/my mind is racing slightly etc. Maybe just for a 3-4 weeks, roughly about every 6 months. My perinatal psychiatrist said that was fine.
Every time I take it, it always surprises me how much it gets rid of my PMS irritability (which is severe and I've had since starting my periods age 13). I guess it calms down the system (calming certain excitatory neurotransmitters). But I also notice that my GERD ( I get reflux but not with heartburn- instead I get nasty tastes in the morning- signs of maldigestion) also goes away. Perhaps affecting neurotransmitters in my gut. Maybe it's as simple as by relaxing my mind my digestion works better. But I'm def not always stressed and often have it all the same! And in my job, I like to understand cause and effect and can't find the answer!!! I know it's a long shot but If anyone has had any other similar benefits, or are scientifically minded, I'd be grateful for replies.
