You are not alone. I get more IBS symptoms pre- and during my period. Change of hormones.... Glad that you've quit coffee. I'm 49 and menopausal and the night sweats went away when I stopped the coffee. My twin sister, who doesn't have IBS got her night sweats to stop by stopping coffee too. Anyone who knows me will know that I will suggest excercise, both for depression and IBS. Those endorphines are better than any prescription for depression any day. Natural. Healthy. Plus you feel good too.
