You've got to wait a few months. The same thing happened to me when if first started and I freaked out and called the doctor. She was very sweet and said that it takes 3-4 months for your body to adjust to the medicine and that long list of possible side effects may occur in those months
before your body has properly adjusted. So just be patient. If anything SERIOUS happens though make sure to talk to your doctor. Oh, as a word of warning, those first few months I was a TOTAL b*tch, and everyone I know that's gone on any form of the pill had a similar reaction.

So don't freak out if you notice a little bit of a change for a few weeks to a few months.
