Just so you know.. DO NOT USE CORICIDIN. IT HAS BEEN SHOWN TO FUCK UP YOUR LIVER AND BRAIN. PEOPLE HAVE DIED OFF OF IT. And I think that a healthy amount to do DXM is about once every 3 weeks or so. Personally, I don't see why you would want to do more than that.. I like to just chill out after a DXM trip for a while and not really do anything.
