Hi Hen. This is an interesting subject(for me at least). I have been peri-menopausal for a few years now. I have always struggled with PMS and it feels like it has just gotten worse for me. I have recovered from so many of my chronic TMS conditions and this is the big one I have been grappling with. I have done a bunch of research on menopause because I really do not want to take any kind of hormones and have been looking for alternate remedies. So many of the books I have read for menopause talk about how important your mental outlook is, getting enough sleep and exercise, meditation, yoga... In fact one of the books is called "Mind over Menopause." I wish I had a clear answer for you but I do know all of things you do to take care of yourself for TMS(not beating yourself up, experiencing your emotions, reducing stress, mindful meditation... should help your PMS). For the last year I was getting a right sided headache and pain in my right neck/shoulder a day before my period started. I tried not to worry about it or give it too much attention because I knew it was short lived. I haven't been getting those recently even though my PMS symptoms have been increasingly severe. I am seeing an accupuncurist to help me through menopause and that seems to be helping. When I was divorced from my first husband 11 years ago, I noticed that I had an especially hard time emotionally during that time of the month for about a year. I was studying Ekhart Toile a lot and the homeopath I was working with recommended that this was a very rich time for a woman to explore her emotions. My homeopath said that I should schedule that time to reflect, write, explore, and to fully feel what comes up. Just what is recommended for TMS! So it would make sense if our emotional side is a little closer to the surface, and TMS is trying its best to distract us from something emotional, that our symptoms would be aggravated.
