Tracked pmdd issues for about 5 months, then went to doc for blood test to check hormone levels (vitamin D is a hormone!).

deficient in Vitamin D. Started a high dose about two months ago and already see a major improvement in physical symptoms (migraines/nausea/vomiting/low energy) as well as the intense mood swings and intermittent suicidal feelings.

Also, I started to use matcha powder (ceremonial grade has way more healthy stuff compared to lattes). Helps all symptoms in under an hour. 

I hope this helps some of you.
