Yasmin and minor side effect

I have been on Yasmin for a few months now and within the first month I had worse dry skin than usual. I dismissed it, thinking that such a minor side-effect was better than the mood swings I had on other pills. (That was why i was prescribed Yasmin--because the pill I has been on before made me very moody). I didn't even think of the other side effect until it became recurring. If I do not eat immediately before and immediately after taking my pill, my heart starts to race and I have a thickness in my throat. I gag and sometimes throw up. Now, I have awful allergies, but I usually have a stuffed up nose. Instead, I am hacking up phlem CONSTANTLY and am wondering if anyone else felt as though they had something thick in the back of their throat making them want to throw up?
