I'm trying to hit the first plateau. I've done second plateau a couple times and I heard that the first is a bit different and I would like to experience it. I'm trying to hit a SOLID first plateau. I weight 178 pounds, give or take 2 pounds depending on the day. I will be using Robitussin Long Acting Cough Syrup which is 15mg DXM for each 5ml and nothing else, although it does say it's 1.4% alcohol by volume aswell but that won't play the slightest role imo. So the question is, how much in mg would I need to take to reach a SOLID first plateau?
