I had taken doxycycline for malaria prevention . After taking it for 3 weeks, I started feeling sick. I was getting dizzy spells and a constant cloudiness in my head. I also experienced anxiety and panic attacks. I felt it difficult to concentrate and was very sensitive to noises.There were days that I couldnt function and just wanted to sleep all the time.I stopped taking it 10 days and am starting to feel better only now. My advice to anyone taken doxycycline is to STOP it immediately. I have spent loads of money trying to find out what was wrong with me
