I took that drug for one week when I lived with my sister. It gave me a headache so bad that I thought it was giving me brain damage. OMG it hurt so bad and it did not let up. My lovely sister told me to keep taking it. Finally after a week I dumped it down the toilet. Sorry your having weird symptoms. I didn't notice anything but the headache but the headache was so severe I doubt I would have noticed anything else.
