You should talk to your doctor about this -- or go talk to the pharmacist if you can't get in to see your doctor right away.

I'm not on the pill anymore because I'm too old (37) and I'm a smoker. The pills I used to take (Ortho 7/7/7, then Triphasal, then Marvellon) kind of messed with my moods (depression mainly) when I was in my 20s. I rarely got depressed once I switched to a progestin-only pill. The hormones in your pill can affect your mind and body in surprising ways. There are so many things that you need to be aware of when you're on the pill. For instance, there can be drug interactions, even interactions with herbal remedies. St. John's Wort, for instance, can interfere with its efficacy. (That's how I got pregnant while I was on the pill.)

So, you should talk to your doc and the pharmacist about all the meds you're taking and ask lots of questions. I don't think a fruit diet would affect the way your pill works, but it doesn't hurt to find out for sure from a knowledgable professional. Good luck to you!
