If you drink undiluted bleach, that's bad and definitely don't drink it. But if you do drink it, try to consider why you are drinking it. If the reasons seem adequate to you, re-think them. Don't make a drinking game out of undiluted bleach. Particularly if your diet is high in ammonia solids, undiluted bleach is no way to wash those down.
Apparently some people say drinking bleach is a good way to fool a drug test. That's dumb. That's fucking dumb, to take advice from somebody whose idea of crafty it is to compensate for all the drugs they take by drinking bleach. Consider the source of your bleach-related advice. Just because someone suggests some activity as something you should do if you've been taking a lot of drugs, that doesn't mean it's a great idea for you. People are different. Sometimes very different.
What happens when you find you simply must drink undiluted bleach, and nothing else you can do helps you see any other option? When that happens, call "time out." Consider calling up someone you trust, to explain to them what's going on with you. They may ask questions. If they ask "Why must you drink undiluted bleach?" - consider the question honestly and with an open mind. And if your explanation confuses or doesn't convince them, try asking them whether they think you should drink undiluted bleach at all. And if they say you shouldn't, hey, consider that maybe you don't always know all the answers? Maybe they're right! They've seen things you haven't, and are able to come at it from a perspective of hey, maybe don't drink undiluted bleach.
If you find you're drinking an awful lot of undiluted bleach and it's a habit you just can't stop, it's possible somebody has given you some other liquid, and you just thought it was bleach. Because if you drank that much bleach, you would have died. Chances are you haven't been drinking undiluted bleach at all. Still, to be on the safe side, find out what the heck it is you've been drinking, and consider whether you should continue with that.
Sometimes you just have to take a deep breath and allow yourself to say "Don't. Just don't drink undiluted bleach."
