You want a great DXM trip without fear of overdose on pseudoephedrine take about half a bottle of an 8 oz. bottle of Robotussin DM and drink a couple cups of coffee. the coffee helps the tussin settle in your stomach and it increases the effects of DXM alot, trust me i made the mistake of tripping and then drinking a cappacino, it was great. just dont drink too much coffee cuz it might cause a very very very intense trip you didnt want. 1 or 2 cups of java should be good. Have fun Peace
