Besides the horrible taste this isn’t all that effective. It might help for an hour or 2 but not much longer than that. On top of that it’s expensive a specially since it doesn’t work well.

I love that Robittussin has a cough syrup that doesnt have DM. My doctor was very specific about me not taking DM due to its effect with my other meds so it was great to find that this only uses guaifenesin.

I was recommended this by my local pharmacist when I had a chest infection. Helps to ease the mucus from your chest easily. It doesn't taste bad and one bottle lasted me quite a while.
