somple solution- just don't take the pill, my parents have been watching me "take" the naltrexone pill since january but i just put the pill in my mouth then push it to the top back of my mouth with my tongue. you can even take a sip of water without swallowing the pill! spit the pill out when they turn there backs and thats a wrap
or if u really wan a try to get clean just do what i said above for a couple days so u won't get sick then actually swallow the pill
