Don't do CC's, its the most retarded product containing DXM. I suggest and I warn you to buy only something with DXM only such as Roobutussin max strength 20 geltabs. Also why not research more for dxm? The doses you did caculated with your weight would only lead nothing but a placebo high rofl. I usually take 20 geltab in 4-5 minutes (5 at a time) and thats 300mg... calculated somehow with my weight I got 56.6 and 300mg divided by 56 is a 2nd platue high, at about 6-7kg/mg, yeah I did my heavy research.. I suggest you do the same.
