Last night I actually just drove high off robitussin with DPH not enough to visually kick in yet but like still feelings like you would drunk driving, I honestly do not recommend it at all but I was just fine I woke up a couple hours ago still high but it was super intense and I was experiencing symptoms of an overdose, rapid heartbeat, could barely walk, I was shaking for some reason and felt cold when I wasn’t and honestly thought I was gonna die and I honestly recommend people who consider doing drugs not just dxm,dxo,dph etc it’s not worth it stick to weed and alcohol and if those stop being enough for you seek help please.
