i tried chuggin my first bottle of tussin (wal-tussin from wal greens) i used to do ccc's but had to quit....i ended up puking and felt like i was coming down off dex for the next two days....couldn't really eat or drink anything....all i did really was sleep....not a fun experience.....unless i can get dex alone i ain't trying it again.....i guess my stomach just can't handle all the dyes and stuff....most people can but some can't.
