Hi I posted a ? on general health today but no response. It dealt with PMS and breast pain(in both breasts) that I am currently experiencing, expecting TOM sometime next week. I've done some searching around this site and I've drawn this conclusion. (Please correct me if I am wrong ). Low Carbing causes a increase in the amount of estrogen in to ones system possibly causing PMS symptoms to be even more promanant , (or less if your lucky) until ones body learns to adjust to this new level of estrogen. Then things should return to normal. I'd like to add that besides the PMS. I am healthy had a slew of tests to prove it last summer, Doc even said so! Too heavy but healthy So what's all this excessive PMSing about? and will it settle down? It's going to have too because I can't be a loon 3 weeks out of 4 every month! My kids and hubby wont have it nor will I! Ellen
