I'm so glad this it's not just my imagination. I have been taking Doxycycline for almost two weeks for ance, always after a meal. Last night I woke up with sudden nausea and and tremendous dryiness all over my mouth and throat. It was very weird and overwhelming! Also, I'm experiencing a constant burning sensation on my skin. Right on my back, my arms, and around my eyes. If feels like a combination between irritaion and ichiness. I'm suppose to take for two months. Hopefully, it be worthed...
