Doxycycline Hyclate and chin area

I have been taking Doxcycline for my acne for less than a week and today, an hour after swallowing the pill with a sip of water and no food in my stomach I felt naseauted and dizzy to the point where i could not stand up. Five minutes later I vomitted and had to call in sick. I am wondering if it is worth it. I don't want to fear taking this pill everyday, but want to get rid of my acne. The side effects should be written on the side of the prescription, but they are not. I am skeptical about this drug.
