Are you taking the pill in the morning or at night? the first month i took it at night and i had no side effects. this month because its easier to remember I started taking it in the morning and I could feel all the side effects. I got headaches but they've stopped now. the worst side effect I have is that during the day I have huge mood swings and I get angry and sad very easily, I'd take headaches and naeusea over that anyday. Stick with it, eventually your body will adjust.
