all sympathies believe me,it's just horrible:-( Otex does work in the long run. The fizzing sound is good because it means it is working on the wax to dissolve it. Previous things like olive oil,softened the wax,but it still had to come out either by sluicing or working its way out. I'm like yourself, using earplugs cos of the curse of snoring! Don't sleep on your deaf side though! Put the drops into your blocked ear,and lie down on the other ear so the drops can sink in ! Makes sense
