Sleep
- Worth itSome hassleReviewed Robitussin DMon 2/9/2020Made me sleepy but that was a plus, and I actually got good sleep. Taste is awful, have something good tasting to chase it with. Had an upset stomach, could have been from other things taken as well. Suggest don't take on an empty stomach. Helped get rid of my wheeze, loosened my chest, and I was able to have infrequent but productive coughs. Worked very well.66WomanNot sure how longWould rather not say
