And I need to do something about it. I've always suffered with PMS but before I had kids I could just bury my head in my work and hide away on the sofa with a box of chocolates. Now, I need to be there for my five year old, without being shouty, irritable and just a miserable person. It's like I change completely. I go from being kind, compassionate and patient, to completely intolerant during the few days before and first days of my period. Has anyone found anything that actually works?
