I took ONE of these acne pills at night (as directed) and woke up feeling very very dizzy. Literally the room was spinning as if I had just been spun on one of those rotatable chairs. Naturally from such dizziness arose a constant feeling of nausea. Of course I stopped taking this drug immediately... however it has been 5 DAYS NOW and I am still having dizzy spells, especially whenever I bend over. Of course it being the holiday week and all I will have to contact my doctor on Monday. I was never warned of such a drastic side effect. CONSUMER BEWARE. I'd rather deal with the acne than lose my equilibrium.
