Im fighting a terrible battle between cold sores on my lips, lip sunburns and a sore throat. Only prescribed 15 tablets and stopped at 13. Haven't had any tablets ( they don't really make much of a difference for me, but I recently found out they need to be taken within the first 3 days ) at all today and would like to cure my throat. Would it be ok to take NyQuil today? Last acyclovir was taken yesterday at around 9pm.
