PMS/ PMDD treatment advice.

Ive been diagnosed with PMS but I think its actually PMDD. Im wondering what treatments have worked for others? I have depression and I have been on antidepressants but I always get vertigo as a side effect so I am looking for something different. I am going to the gym and trying to eat healthily but part of my symptoms is craving food.
I cant go on the pill because I am lactose intolerant and I've tried the Mirena but it hasn't helped alleviate symptoms.
Any advice on what has worked for you would be great.
