I mean I know I've smelled it..it could have possibly been whatever it was cooked up with or the type of stuff he's using in his stem to smoke it. You are NOT alone playing the fool. Before my fiance went into treatment I would do anything and everything for him. I believed all the lies too for a while. So we all play the fool when falling in love with an addict. And as far as the no libido I can totally relate that to the drug use because when smoking crack it does something to their sex drive my fiance and i were intimate pretty much everyday before he started using..its like it consumes their every thought. Coughing may not be directly related to the smoking but to clear his throat rather..ive noticed that before. Perhaps its not crack if you say he was carrying water all of the time? That sounds more like a drug youd mix with water and shoot up rather than smoke. but we'll never know for sure. Message me if youd like and your NOT alone
