The pill can definately make you nauseated and also cause headaches. Feeling nauseated in general will make food unappetizing. Maybe you could try a different type of pill that might not have as many side effects. I have tried a few different kinds and they all seem to act a little different for me. Ortho-Evra made me cry all of the time. Another one I can't remember what it was gave me really bad headaches. Then Yasmin made me feel good but had sexual side effects such as loss of labido. I now use Microgestin and it seems to be working well for me without any pesky side effects.
