i do it alot, too much, 3-5x's a week for about 6 months now. ive noticed some cognitive problems as well as feeling generaly 'out of it' even when im not tripping. but no bad phyisical reactions. its not recommended to do more than like twice a month, but im a fool and i know the possible dangers im putting myself into.

so if you do dxm use products with only dxm in it, and try not to make using it a regular thing.
