While I've never tried bleach, I have tried drinking something else. I'm new here so I don't know if I'm allowed to say what but I'll omit the detail regardless. I wouldn't recommend it. Even if you did manage to get it all down like I did, your throat will become raw and irritated, you will start sweating profusely, you will throw up, and it will land you in the hospital among other things that will make your life worse than before the attempt. Trying to OD on your medication was also unlikely to work. I've tried that one too. I understand the desperation of wanting to do anything to get out but it really is more difficult than you'd think.
Be careful. You don't want to do anything that will make you suffer more than you already are.
