To be honest if she's as bad as that, i.e. trying to kick you etc then I think the regumate or marble would be your best option, I have a 'moody mare' for a month or so in the spring, started last year and the first thing my vet suggested was ' keep a diary for a month and if she doesn't settle we'll try her on regumate. I was shocked in all honesty as would have at least expected a scan to rule out cysts etc, thankfully she settled down and as we don't compete I can live with her moody behaviour for a couple of months each spring, she isn't as bad as your girly though.
Hope you get her more comfy soon , can't be nice for either of you.
