Cold sweat caused by DXM use?

I just recently had a period where i used dextromethorphan recreationally every four-six days for about a month(not smart i know:rolleyes: ).
My sources were OTC preparations with only DXM as the active ingredient.
Ihave not used in it in two weeks yet i still occasionally suffer from a strange cold clammy sweat,once i woke up to find my face and neck covered in an oily sweat as if my pores had gone nuts.

Whats causing this? I’m taking vitamin supplements and eating well but still it bugs me.

Not sure if I can link this page or not, but you may want to take a look at this http://www.erowid.org/chemicals/dxm/faq/dxm_side_effects.shtml it should also be mentioned that bromide can build up in your body and cause problems on it’s own.
