I hate Birth Control

I very recently started taking the pill. So far I've thrown up quite regularly because of nausea (which I already struggled with but not like this), wicked cramps, killer headaches and a few other symptoms. My doctor said it is perfectly normal and I'm just having a more extreme reaction to it, give it the first three months and it will all be over with. But I actually hate it. Any advice? I need help keeping these symptoms at bay. Anything that would help with the nausea especially is greatly appreciated.
