hi friends, frankly i knw very little of all u speak of, the patches and the varieties of scd. But what i do knw is that i am addicted to pentazocine, i administer it even when i dont have crises. I knw this is vry bad for my health both short and long term and besides it leaves me penniless most times. I really need help, knowing i have to stop but how to accomplish that eludes me. Another thing is: its like most members here hv easy access to hospitals and medical facilities maybe coz u are either in europe or america. Well i am in Africa and one cant easily have access to hospitals over here. One more thing, have any of u guys experienced the foot ulcers, mine has lingered for close to two years now and very painful. Your suggestions pls.
