The Birth Control pill turns my wife in Mrs. Hyde if you get my drift, so that could cause some serious changes in your mood. Also, do you suffer from anxiety or depression? If it is anxiety then you need something that helps with that:
Herbs like Kava and Valerian help. Peppermint tea is awwesome for stomach anxiety.
Drugs like Benzos: Xanax, Klonopin, etc. are for anxiety and that alone and they do work to some degree although everyone is different.
If depression is the problem then SSRI's may help. Anyway, my point is that you should get a second opinion on your meds and see another doctor as well.
Seriously, I have two kids now becuase my wife can't take birth control. LOL. I am just kidding they were both blessings, but seriously, she looses her mind. LOL.
