never available my questions are do I change my toothbrush every week while I am on treatments? do I through away lipsticks or lip balms? or mascara? is it okay to take melatonin? and last is it okay to take advil liquid gels my doctor told me to take Tylenol but Tylenol does nothing for me? one more thing is it better to take harvoni in the morning or at night I already have problems sleeping. I am starting harvoni on Monday.
