I just bought a bottle of Tussin Maximum Strength for a first-time trip. I checked up on some of the doses people are taking in here and it seems to be around 500mg or more. I went there and bought a bottle with 118ml which turns out to be about 354mg. Is this worth taking, or a wasted trip? Seeing as how im too lazy to go out now and buy another bottle, should I wait until I do or take it now?
