"when i started taking it in december, i felt emotionally great but the side effects were horrendous. at first i felt great, but then i felt really nauseous and i couldn&#039;t eat anything but buckwheat. thinking about food made me even more nauseous and i had really bad diarrhoea. for some reason after taking vortioxetine, i became lactose intolerant. i experienced heartburn while taking them. although i felt emotionally more energetic, my body didn&#039;t like it at all."
