ARXT: Mucinex: My experience with Guaifenesin showed me that the best combo is 600mg combined with 30mg Dextromethorphan HBr, both in an extended release tablet. I have never found Guaifenesin to work well alone after some 30 years of trying. Also, you cover several causative bases by adding the DM.
Mine comes from KV Pharma / ETHEX Corp.
(side note: pseudoephidrene/Sudafed is the only drug considered safe while diving by the USN.)
