I hate the menthol ones, but the ricola herb drops are the shit. Obviously they aren't going to numb you up as hard as the menthol ones, but they feel helpful without being overpower.
My colleague gave me one of hers this week. She told me they were the good stuff. They were so strong I wasn't sure which was worse: the cough drop or the sore throat. Checked them out at the store today and they have 20mg menthol! The ones we call "the good stuff" only have 7.5mg.
