Yeah, i used to drink robo. And it made me puke everytime too. It's such a disgusting taste/texture. smelling it even makes me gag. I'd have to say, delsym is alot better tasting, but it makes me gag still(not as much) sometimes i dont gag, and can down the whole bottle in a minute. I have puked from drinking delsym though,both times i layed down for an hour waiting for it to kick in. Don't lay down to wait for the effects as the cough syrup is at the top of your stomach making it easy to expell the syrup,and ruin your trip. Atleast sit down, or stand up often so the syrup can run through your stomach and not stay in there too long.
