I started taking this on a Tuesday (Twice a day, 100mg). I made it until Saturday before I quit. This drug made me feel so out of touch with reality and in a dream like state. A very unpleasant dizzy dream like state. Also somewhat nauseous with a constant slight headache. Today is Wednesday and I still feel like a fake version of my self. I missed work yesterday and part of Monday. I am starting to freak out, I have never reacted this way to antibiotics before. It is taking so long to get out of my system.
