Hey all, and especially OP, please do a site search of SN and brain damage. I recently posted in one such thread that nitrite protects the brain, which is why people recover without brain damage. I attached links. You can search with my username. If I recall correctly, rats were discussed in that thread and that's what pissed me off and got me to searching for reliable information, so maybe use rats as the search term with me as the user. I'm on a tablet and have a spotty wifi connection, so it's more effort to do all the searching and linking than I have the energy or motivation for, but I've given you enough information you should be able to find it pretty easily. And honestly, I read just a handful of the comments and I get drained by speculation, after a certain amount of time it just gets old. I care enough to say something about it and say where to find the info if one is motivated to put in the effort if they really want to know. I do wish y'all the best, I'm just in a bit of cranky old lady mode tonight, I genuinely don't mean to shame anyone, and I do care that y'all get (and give) accurate and helpful information to make the most reasonably informed decisions one can, as any suicide attempt is a big risk.
