I have to take Doxy for 2 weeks twice a day. I have all the same side effects as everyone has listed here... very down and depressed, itchy pimple rash all over legs, face, neck, chest and back of shoulders, cold sores, severe headache, bloating, stomach pain, tiredness, lack of interest in anything, dry mouth, tingling toes and anxiety. Can't wait to finish the course, but am disappointed to read that the side effects carry on after stopping, does anyone know how long it takes for them to subside?
