So I found some generic brand cough cold medicine tablets with the same exact ingredients/amounts as DayQuil, which is 325 mg of acetaminophen, 10 mg of dxm, and 5 mg psuedoephedrine. I?m a lightweight, like 100 pounds and am wondering if it is safe to take? I was going to take about 10 pills to get a decent high, since it is my first time, but am worried about the high levels of acetaminophen possibly having adverse effects. How many tablets should i take if any at all? I?m aware that i can buy stuff with just dxm and no other ingredients, but i really don?t feel like going to the store since I?m under 18 and idk if they will decline me.
