i take kariva now and have been for the last 3 years and my pms and mood swings are crazy. The week before and a few days into my period im up and down like a roller coaster. I can't take it any longer and am looking for somethings else cause if i don't im sure my boyfriends is either going to kill me or find someone else. other then that its been good as far as weight gain, maybe a few pounds when i started taking it.
