Codeine Cough Syrup

[highganja99]

SWIM Would like to know if any SWIY's out there have an opinion or information relating to the oral use of Codeine Cough Syrup containing seemingly high amounts of Aspartame ,Sorbitol, Sodium Benzoate and Azorubine (Carmoisine) - (Red Food Colourant) ? SWIM dows know the effects of Sorbitol and Sodium Benzoate already and is mainly asking about the aspartame and red colouring.
SWIM knows that there was a study linking sodium bezoate + food colourings in combination to hyperactivity. SWIM wants to know mainly if Aspartame or the Red Dye may change the experience or add unwanted side effects.

BTW the Syrup is 10mg Codeine / 5ml Syrup in a 250 ml bottle. Swim usually takes half a bottle for his dose.
