"I am a first time user: Extreme fatigue for the first few days taking it. After a few weeks of dramatic mood swings, the nausea around period week woke me up in the middle of the night! Waves of nausea that didn't allow me to eat for almost entire day. But, I'm still sticking it out- no weight gain, I've started taking B-complex which REALLY helps. Oddest side effect is I no longer have desires for coffee (it makes me more tired) but am now frequently very thirsty."
