I also experience severe PMS. I used to get really bad cold sweats, vomit, and the works. I took birth control for a year and the physical symptoms have gone away but not the mood symptoms. I just started my period today actually and thank the stars that I did lol. I was in a deep depression for the four days prior to starting. Now that my period has started I feel much better. There is still some depression but I do feel like I can see light again. I'm not really sure what can be done about it besides maybe going on birth control again.

I take an antidepressant and an anti psychotic. They work wonders but I guess m hormones are just way out of control right before I start my period. I've been diagnosed as Schizoaffective too. And it seems that depending on where I am in my cycle determines how forceful my psychosis is.
