I began taking Yasmin 4 months ago and it has been hell!!! It took me a couple months to realize the connection (my roomate went on Yasmin at the same time and I thought SHE was nuts saying it made her sick!). When I first start taking a pack each month I'm extremely nauseated and it lasts for about a week. Then, I feel good for about a week. However, the third week is when I turn into a raging b*@ch! I have uncontrollable mood swings, cry over nothing, and snap at people for no reason. The worst thing about that is I know I'm flipping out over nothing! I've lost a bit of weight since going on Yasmin but I attribute that to the fact that I'm also eating healthier. I used to be on ortho tricyclen and I loved it except for the weight gain (130-165 in about 2 months) but I'm thinking of going back to it anyways (i'd rather be fat and happy)!!! I thought I was crazy thinking Yasmin was the reason I was moody and felt like throwing up but after reading all of your posts I feel better knowing I'm not alone! Good luck to all of you!
