I have had the motion sickness as well, but not as much, my sympotoms like to change, I dont know why though.
I was reading this site and it was showing all symptoms of menapause and out of 34 symptoms, I have like 28 of them!!!! and I'm only 31!!!!!!!!

It just cant be that, but I thought maybe I was having anxiety cause of a hormone imbalance. Cause it seems to get worse the closer I get to my period.
