"Do you think if you suffer with PMT yourself that it would be a nightmare owning a mare??????????????????? "
Isn't EVERYTHING nightmare for women who suffer with PMT ?!?! At least for a number of days every month? LIFE just isn't really worth living when you suffer with PMT, is it!?
But unless you suffer with it more than a few days a month I suppose mares or geldings, it won't make much difference from the point of view of PMT. Avoid all horses and other sensitive creatures whilst suffering is my advice - it's not fair on them
