Never had an constipation issue with any opioids (I can evacuate the day after consuming 200mg loperamide, no tolerance. However, there is on exception: when I when I was recieving 380mg a day of intravenous methadone after being hospitalized for a major injury. While this amount of methadone didnt constipate me much orally, having it IVed everyday for over a week did (the idiots gave my regular oral dose, but intravenously).
I remember this fucking filipino nurses aid telling me to hurry up after I painfully made my way to the toilet, and had a very hard time trying to take a shit. She was shouting at me to hurry up, even calling me a "fucking junky". God I hate filipino nurses, and most filipino women in general (there are exceptions). If I had enough strength I would have punched her in the face. Generally I am not violent to women, but female filipino nurses/bitches are the exception....
