Well I was digging through my pill cabinet just out of curiousity, and I found a bunch of Zyrtec-D's from when I had allergies. I was about to chuck them, when I saw that they contained pseudoephedrine. I knew that pseudoephedrine is a precursor to the synthesis of meth, but what I didn't know is that it supposedly has the same effects of ephedrine, which is known as herbal exstacy. So here's my question, I have no clue about dosage, and each pill contains 120 mg of pseudoephedrine, so how many pills should I take to feel the effects?
