Dude come on, you made a thread a couple weeks back complaining of worrying heart issues when on DXM. I'm not trying to scold you or anything but maybe you should just quit taking the DXM, find something else that doesn't cause you to constantly worry about your heart. I find that methoxetamine feels alot less taxing on my body as whole and the experience is similar in a way but just plain better, ymmv. For the vast majority of people the doses you list are within reason (for recreational doses that is). How's your health? If your heavy set or have a family history of heart issues DXM may very well be causing some strain on your heart but since were not doctors and don't know your physical health it's anybody's guess. Be carefull, listen to your body.
