Hello John
Welcome to Pherotalk 
I am not sure mones can help you with this problem. It depends on how serious it is and what is causing it which you do not need to share.
I do suggest you read What pheromones can and can't do: realistic expectations for newcomers
Mones can influence her behavior but they can not change it totally. You seem serious about wanting to save this relationship so its worth a shot.
I need to know a few things and if they are to personal you can just say “no comment” and I will understand.
Does this problem occur all the time or at certain times of the month ?
How old is she ?
Was she always this way or has it suddenly occurred ?
When you say emotional do you mean… upset, nervous, angry ??? Which emotion is prominent ?
I am thinking IFM to ease and calm
Ishine to lift mood
IH to connect and comfort
I am thinking about TUTH for arousal but I am on the fence till I know a little more on that one.
Your GC will go out shortly
