I oded on sertraline about a month and a half ago, obviously unsuccessfully, and I would never recommend it as a method to ctb. You WILL vomit. I did almost immediately after getting the pills down, and it's what made my attempt fail. Even at such a high dose, it won't matter if you can't keep you down. For sertraline, they don't usually pump your stomach or use activated charcoal or anything at the ER bc the majority of cases will just throw enough of it up to survive. The side effects are also horrible. I spent a week in the hospital despite throwing most of the medication up because my symptoms were so severe. In theory it would work if you could keep it down, but its reliability doesn't outweigh the side effects in my opinion as someone who's survived this method
