Everyone here is either going to tell you that since coricidin contains something that's easy to overdose on, that any is too many if it's beyond the suggested dosage. Others are going to say, don't do dxm its stupid. If I were you I would never take coricidin. There are other pills and caps out there that contain only dxm as the active ingredient. Take a look around. Rite-aid has a cheap bottle(4bux) that is 300mg worth of dxm and its only dxm.
Dear god no. Thats where they keep the full strength crazy. Seriously dont fuck with it. It ruined DXM for me forever. Take robotussin cough gels, they have only dxm and a small bottle will get you fucked off your gourd . . .
Swallowing all those big gels is not easy for everyone. I would never want to trip on DXM bad enough to take those fuckers again. I've tripped on CCC's many, many times, probably too many, but the trips were always extremely fun and crazy. However, it really isn't a good idea to use DXM in the CCC form, though it is by FAR the easiest method there is. Coricidin can destroy completely your ability to swallow any type of pill and you can end up gagging by just looking at the box in the store. Those little fuckers are small but theres just something about them. The smell, the taste, it just makes me sick to my stomach. Coricidin will ruin you, and not just from the drugs it contains. Anyone who's done it a lot knows exactly what I'm talking about. Start low and work your way up. You don't want to go to the hospital because of the CPM in those little red pills.
Robitussin Cough Gels Robistussin long-lasting (syrup) Tussin MAX (CVS brand) Sucrets (The DXM-containing ones) Those are the only 4 I've ever used straight.
DXM can ruin your life if you're not careful. I went from smoking weed once to being a pothead then to popping pills (mostly triple C's but others as well) and also huffing. But hallucinating I feel is the best part about it. Mostly all of my friends have hallucinated on them and our hallucinations vary alot. One friend of mine seen the police and said they were talking to her, another seen squares that were changing colors, yet another seen a black & yellow robot climbing on the wall, and I seen things moving around (the bricks in this fireplace were moving in and out and the wires and other shit were moving too.) Oh and I heard a secret radio station in the wall. I've hallucinated other times too, I know only cuz I wrote down in my journal that I was but I don't really remember what. I remember though another time I kept seeing my sister and mother out of the corner of my eye. It was weird. [EDIT: I no longer huff or do triple C's. I tried them a few times since getting out of rehab but I'm done with them...I'm onto better drugs. Ones in which I use only in moderation (except weed, which I do everyday, but I don't count that as a drug.]
